I agree...  My images were both mandelbrot zooms..  I just can't get
enough.. :)  I guess this
is because Mandelbrot's & Julia's are deep-zoomable, and the Mandelbrot set
is infinitely more interesting than all the Julia sets combined, IMHO :)  I
was *extremely* surprised to see that I actually got 2 votes for best
overall, one on each of my fractals.  (Octobrot and Pulsar were mine, just
to let you know <g>)  I had a question, though...  This is a comment I got
for Pulsar:

>Utterly amazing image.  Barely ekes out 215(Octobrot) because the
circular shape drawsthe viewer in... I'm sure I know who createdthis
because it matches (really, exceeds)the beauty I've come to expect from
your images...  Also one of the best uses of color- I feel that if I
were to touch it, I wouldfeel the ridges...

I don't really want to know who wrote this, so much as who the author
thought my fractal was by...  (I don't want to push it though..  If you'd
rather not tell, I don't mind <g>)  I'd be *extremely* flattered if it was
Damien or Wizzle or anyone else known for cool fractals.. :)  (Don't be
upset if I didn't name you, they were just 2 people off the top of my
head...)  To tell you the truth, the real reason I'm so surprised is that my
entries weren't specifically designed for the contest.  I just picked them
out from the heap of fractals I'd designed.  Octobrot was really my
favorite, but Pulsar was nearly random...  I just scanned through a few
until I saw one I liked.  If you really liked those, just let me know..
I'll post more pars, or eventually, if I have time, I'll put the images on
my web site.  Pulsar wasn't nearly as good as some others I've made.  I've
been reluctant to post alot of pars, because almost all my images are deep
zooms, and have taken a long time to draw.  Unfortunately, though, I haven't
had time to play with fractals much lately, since I've just started college
(FSU, I'm a freshman <g>) and getting adjusted has taken alot of time.
Speaking of which, I need to get the A/C fixed in my apartment...  I guess
I'll see y'all later!

Actually the Mandelbrot set is *exactly* as interesting as all the Julia
sets combined!
Benoit Mandelbrot discovered the set as a visual index to all the Julia
sets, and it is mathematically true that any small area of the
Mandelbrot set resembles a corresponding area of a corresponding Julia
set.  (Maybe some of the list members who were not so lazy as to give up
maths at the age of 22 can explain more.)

I agree, although I would phrase it differently.  I think a lot of
appreciation of fractal images (both creation and judging) is influenced
by what's new and unusual. Most Mandelbrot images aren't new or unusual
to even slightly experienced people, and I feel that we unfairly
overlook them.  Such a category shouldn't be aimed at beginners!

I suggest the category is called "Quadratic".  The basic iteration
formula z -> z^2+c which is used in classic Mandelbrot and Julia images
is a quadratic polynomial.  A huge variety of images are possible with
varying colouring methods; the "beginners'" category would perhaps be
plain escape-time iterations colouring.

Joe

On the other hand, the winners chosen in the 1997 FractInt contest were almost
all "familiar" Mandelbrot images even though there were many very unusual
images entered.

Congratulations all around for a marvelous contest!  I'm glad that people are
putting the fractals they made and the fractals they considered, but did not
enter, up to peruse. It seems like an open-house walking tour of artists'
studios-great fun!  

I'd like to say Thank you! to the folks who voted for and left comments on my
entries (Eggsellent Spiral, Robotic Surveillance, and My Belfry)! I hope the
emphasis on the commenting carries forward to future showings-whether they be
contests or just periodic non-competitive overviews of what everyone's working
on at the time, it's valuable feedback.

Thanks again Damien, Kerry and Paul for throwing a great bash!

Subject: (fractint) Currency crisis
Date: 02 Oct 1998 17:51:47 +0200

I had several versions of this entry.  The one I finally picked didn't
get any votes (although it did get the comment
Are you perchance a resident of one of those countries that has 
recently undergone this? ;-)
- exactly!  Although they are not the actual gold coin, the Krugerrand,
because the gold price has held up fairly well.)

I picked it because of the way all the gold discs vanish into a black
hole in the middle, but my wife thinks it's the worst one.  It's the
last of the following pars: the first 5 are variations on the colouring
on a different part of the fractal.  Comments anyone?

A small credit: the colour values are cribbed from Wizzle.  The placing
is my own hard work.

Actually, I understand the reasoning, but I never really thought about it
that way...  That's kinda funny :)  Well, a tiny area of the Mandelbrot set
corresponds to a Julia Set whose 'c' parameter is the coordinates of that
area in the Mandelbrot set.  (The _whole_ julia set, not just a tiny part...
That's because Julia sets are so regularly self similar.)

Copier? :-)

Don't bother trying. Globalserve's web server is misbehaving and so is its
ftp server, and they have been for 48 hours. "Disk crash" so they tell me.
Called tech support about it again just now...the robot kindly told me
their servers were back up (which they aren't) and then put me on hold, and
after 30 minutes, I deduced that irate customers were ringing down the
phones demanding they turn the machines back on & stop lying and so instead
they scurried off and took refuge in their coffee room...
I hung up and sent their administrators an email.
Anonymously.

>It turned out that my first use of Ken?s tool was to sort my entire set of

Lost my system files when I upgraded to win98 (be careful with fat32 upgrade).
Its taken me almost a month to get my system completely reloaded and working
properly.  

Bill,
I've been off line for a while and need to catch up on my reading so if this a
tired request let me know.

I tried the perl script that Ken posted and I really didn't see any
improvement in trying to import the par file into Access.  I was wondering if
you can post your tuned perl script for parsing. Does it require a cammand
line outfile name?  I think there is even an utility to make perl script
executable for others on the list.  

maybe Ken and you can offer some insight into what I'd like to do.  I don't
know if you can call it parsing but I'd actually like to create an outfile
file that is space delimeted with the different cammands stripped off.  This
way I could then import the data into a data base.  I think that in the perl
script we can goe after the litany of possible comands in order and provide a
NA entry for a command not used in the par.

Thanks ahead of time for any help and as usual 
Best regards
Rui

Hello, all--		

Here are 14 pars based on Kathy Roth's "Gravistalks" formula.  This
formula is very versatile; I used the same set of numerical parameters
for all & cycled through various combinations of functions.  They all
generate relatively quickly, too.  I THINK I've figured out how to post
properly...

Jo,

Thanks for posting those images--you've got some really nice work there.
I think it's good to periodically return to the basics, as you have.  This
will become apparant when I post my next batch of formulas.  :-)

 The omission of program source info. for images 91,95 and 168 in Paul's table
resulted from my assumption that if no source was mentioned it would be assumed
that the images came from my own software .Other contestants were more curteous
. My images were generated from simple  BBC BASIC V listings which were
customised for each different version. I will shortly place images 91,95 and
168 along with some other JPEGS generated for the contest but not selected, on
my website. If anyone is sufficiently interested to try and extract information
from my listings that would allow generation of these images with Fractint
please e-mail me direct. I am not able to do the conversion myself. All 3
images were generated using much larger palettes than Fractint supports.I would
also be interested to communicate with anyone interested in the conversion of
fractint .pars/.frm files into BASIC.

The below par is something of a preview of a _possible_ posting to abpf

bit of modifying as I have been doing recently to some other fractals...

Well, Jim started it, when he said he didn't even understand some of his
own formula's. So I started playing with one of them. 2 days later and
with the help of an unknown person's color map, I came up with this
image.
Why couldn't I find things like this BEFORE the contest?  :)

Subject: (fractint) NEW FORMULA AND PARS :-)
Date: 04 Oct 1998 20:36:32 -0400

Browsing Spanky I discovered a web page where someone had generated a single,
somewhat interesting Julia set from the Riemann zeta function. I decided I had
to have that formula, and manufactured a Fractint frm that uses a good
approximation to the zeta function. I was able to replicate the images on
the website.
Thence I added a "+c" to the formula to create a variable parameter; there
may be interesting
Mandelbrot images to go with these, eventually.

Some notes on the different passes options here:

1,2,3 passes give exactly the same picture and 1 and 2 passes should
take the same time (more or less). 3 passes does a rough pass first
and then throws the data away and does normal 2 pass, so that should
take slightly longer. In all cases every point is evaluated.

The g1 to g6 options are just like normal guessing, but at a lower
virtual resolution. The quality of the image is just like rendering
smaler pictures and then enlkarging them.

Tesseral, guessing and boundary tracking are not evaulating all points 
allways. Some points will be guessed and thus evaluationtime will be
saved. The quality of the image will vary on the part of a fractal
rendered.

Guessing has very little overhead and thus is unsually the fastest. It 
can guess wrong, especially with sharp pointed shapes. When zooming
into areas with many sharp edges, errors can distord the image
considerably.

Tesseral is usually more accurate than guessing but has to evaulate
more pixels before guessing. This is usually slower than guessing.

Boundary tracking is a method that shouldn't show hardly any errors in
its estimation. It won't work for unconected fractals. It also has
problems with distance estimation of the M-Set and with the interior
of the M-Set altogether. A high maxiter helps a lot, but errors can be
seen there first. Boundary Tracking has a lot of overhead during
execution, but it estimates more points than guessing. For
floatingpoint evaluations the Boundary Tracking is usually slower than
guessing, but with high maxiters or deep zooms its usually faster
(since the overhead is irellevant compared to the evaluation of a
pixel).

May the Source be with you.

Exactly. In fact the more they dis-resemble fractals, the more I am
fascinated by them. This one has the gritty texture on chalk and iron oxide

Sorry for the delay. I have been traveling for business and I just got back 
this weekend. Makemap is a Windows program for designing color maps for 
Fractint. There are a large number of options for generating a variety of 
color maps, with many parameters that can be varied. The color map can be 
displayed in the same format at the Fractint map editor, and also as a 
bull's eye, which gives a better picture of how the colors blend.

The problem is due to the line breaks in the two long formula lines.  If
you concatenate those two long formula statements so that they are each
one line, then it should work.  It did for me in xfractint, but I
haven't tried with the DOS version yet.

I had the same problem. I opened zeta in Word95 and found the commas in the
ERROR Satements corresponded to end-of-line marks (returns) in the formula.
When I deleted the returns, ZETA produced fractals in FRACTINT.

Hi Kerry,

>>Thanks for posting those images--you've got some really nice work there=
=2E
Thanks.
It's amazing to explore the mandelbrot-set, but it's very time expensive.=

The longest image I generate for a friend of mine needed 1600 hours on a
P133.
I added a page 14 to my site with a Mandelbrot of the Week.

Cheers --Jo--

What??? It works fine in my copy of Fractint 19.6. Are you sure you didn't
add extra spaces or line feeds when you extracted it? There are two very
long lines in the formula, if you just selected and copied and pasted out
of a window they may be truncated. I recommend saving the email directly as
a text file, editing it and stripping away the extraneous text, twice.

Unfortunately, I don't...

Subject: (fractint) Strange Attractor category
Date: 06 Oct 1998 10:20:54 +0200

!!!! See the list of IFS coefficients below !!!!

With this email I would like to respond to the comments I received 
from the images I posted to the Fractal contest. These three images 
where of course the three black&white pictures "Helix", "Worm" and 
"Vortex" (resp. images 82, 83 and 84).

First of all I want to thank the people who voted on one of these 
three pictures and even made "Helix" the winner in the "Strange 
Attractor" category. I also thank you for the flattering comments 
you gave on my pictures. The comments also posed some questions 
about the pictures which I want to answer here.

First of all how are these pictures made? They are 2D IFS
(Iterated Function Systems) which could be generated with 
Fractint, but which I made with a program I wrote called Dust 
fractals. Dust fractals is primarily intended to generate Strange 
Attractor type fractals.

Strange Attractors are fractals where pixels are not colored
on the behavior of the orbits of points (as in escape time
fractals) but where the orbit itself is displayed. To be more 
specific, with escape time fractals (e.g. the mandelbrot set)
the coordinate of every pixel on the screen is put into a 
formula and iterated, the pixel is then colored according to 
whether it escapes to infinity or is bounded. With strange 
attractors a single point (or multiple points) is iterated and
the points of the orbit itself are displayed on the screen.
The pixels on the screen are often colored according to how
many times they have been hit after a certain amount of itera-
tions have been performed. Examples of strange attractors 
generated by Fractint are: IFS, Gingerbread man, Icon.
This explanation is not very scientific I guess, but it's the 
way I see the difference between escape time fractals and SA 
fractals.

As said before the pictures I had submitted to the contest where
generated with Dust fractals. This program for Windows 95 and 
compatible systems, is still in it's developing stage. Fractals
which can already be generated are: Gingerbread man, IFS, Flame, 
icon, hexagonal and square quilts, Mandelbrot cloud, Pickover 
fractals, Henon, bifurcation diagrams and the Mira fractal. Some 
nice features of the program which I like to point out here are: 
Truecolor support. Arbitrary resolution and bilinear resampling. 
A non-linear relation between the number of times a pixel is hit 
and the color of the pixel is possible when displaying the cal-
culated fractal, this means colors can be more evenly distributed 
when the contrast between much visited and less visited parts in 
the fractal is too high. And generation of random fractal 
parameters sets, this means that you can with one push of a button 
generate for example a totally new Icon fractal, or IFS fractal 
(see the IFS coefficients below for some examples!).

For further development of the program I would like to call in 
the help of other fractal enthusiast. First of all for beta testing,
suggestions and error reports from both experienced fractal artists 
and newbies would be very helpfully in further developing Dust 
fractals. Secondly I could use some help from someone more familiar 
with the mathematics behind strange attractors and mathematics in 
general then I'm. As mentioned above I have build a feature in 
Dust fractals to generate random fractal parameter sets, for example 
for the IFS type fractal. The algorithm behind this feature is not
as advanced as I like it to be, resulting in the fact that you have 
to push the button a lot of times to get a nice picture. If someone 
could review this algorithm and come up with better ideas this would 
be great.

If you're interested email me at:  thomas.middelkoop@cmg.nl
so we can work something out.

Finally I want to share a small number of IFS parameter sets I 
have already generated with Dust fractals. I recommend to use
the gamma1 or gamma2 colormap with these fractals since black&white 
works very good for these type of fractals.

Date: 06 Oct 1998 08:06:19 -0400

Thanks for all the nice comments on this fractal. People seemed to think it
fit the category well. Some asked if it really came out of Fractint. Two
comments point out the 1920's, 1930's feel to the image.  I agree, when I
got to that point in rotating Linda's color map, I quit because I got the
same impression.

I've included two other pars from the same formula. They are not nearly as
mechanical. (In fact, I could not find any other par with this formula that
had anywhere near the same sense of engineering.) Note that each instance
uses the potential parameter, one way to get rounded surfaces, of which
there are plenty in these images.

This really shouldn't be very difficult.  I'd just need a list of all
the possible entries in the par file.  It shouldn't take more than a few
minutes (fingers crossed) to modify the one I originally did to do this.

I'm either doing something wrong or I'm still to new at this to

that were included in the original posting they all appeared to be the
same.  (Of course they all defaulted to Mandelbrot) I tried to add in a

formulaname=ifs
but then I get errors that the arguments are not understood.

I can certainly be e-mailed directly.

Thanks. That did the trick. I should have seen that before :-)

In reply to some problems with the list with IFS parameter sets
I had send to the mailing list.
In order to use the parameter sets in fractint you should save my
email as a *.ifs file (e.g. dust.ifs) and put this file in the main
Fractint directory. After starting up fractint you press <T> to go 
to the fractal selection screen. Select the "ifs" fractal type and 
press F6 when you are in the IFS selection screen. Finally select 
the *.ifs file with the parameter sets.
I hope you can solve the problem of using the parameter sets with
these guidelines.

greetings, Thomas.

Fifty is the total number of messages I get a day.  Usually it's more
like a hundred.  It hurts.

So far, less than 5% are spam.

Date: 07 Oct 1998 14:39:18 -0700

David Shanholtzer and Paul DeCelle  posted some
gravistalks pars-  it was nice to see what other people
came up with!  The p1 parameter in gravistalks isn't
attached to anything and makes no difference so
in gravistalks 2 and 3 I used it for the gravijul parameters
in different ways.

What's the UltraFractal discussion list?  I've been playing
around with some of the true color fractal programs and
I've found that the thing that bothers me about them is
manipulating the color palettes.  It's not so much that the
sliders are not as precise as with the 256 colors but that you
end up changing the colors in the whole image.
One of the most fun things with Fractint is using the
color map to shade from light to dark in a certain
number of colors to bring out a 3-D effect that
might otherwise be absent  or you can bring out one section of
an image and nearly erase another part by the use of
colors.  I don't see how you can do this in the others, unless I'm
missing something.

Kathy,

 - What's the UltraFractal discussion list?

It's the mailing list for discussing Ultra Fractal, a new version of which
is currently in beta (and is nearly done, I think).  You can find out more
about Ultra Fractal here:

    http://www.ultrafractal.com/

And you can sign up for the mailing list here:

    http://www.fractalus.com/ultrafractal/list.htm

 - I've been playing around with some of the true color fractal programs
 - and I've found that the thing that bothers me about them is manipulating
 - the color palettes.  It's not so much that the sliders are not as
 - precise as with the 256 colors but that you end up changing the colors
 - in the whole image.

Ultra Fractal produces 24-bit images but it still retains the notion of
palettes, so it is a little different in its color usage than some of the
other 24-bit programs.  It also includes the ability to "layer" fractals,
it reads FractInt FRM files, and it is pretty flexible.  The current beta
does not include complete documentation (which is hardly surprising) but
the UF mailing list is a good place to ask questions if you get stuck.

Subject: (fractint) Butterfly/Caterpillar Pars
Date: 07 Oct 1998 18:15:14 -0400

A slow day at work, today, so guess what I did :-)

Here's a par based on Miguel Fliguer's Prueba_000 formula.  With a
little bit of 
colormap editing (which I'm VERY new at!), I got it to look pretty
good..

Along the same theme, the second par will (slightly) resemble some kind
of psychedelic
caterpillar.  It's based on Sylvie Gallet's Gallet-4-11 formula, and
it's very colorful.

These'll be posted to my Fractint site, soon.

As promised - or threatened ;-), I've updated my Fractint site with the
Butterfly and Caterpillar images, plus a few other new ones.  It's at
http://members.xoom.com/PaulDeCelle/set5.html

Gulp!  I'm starting to run out of server space - looks like I'm going to
have to decide which images to "retire" soon to make room for all the
new stuff :-(

Re:  1600 hours generation time for an M-set zoom - My deepest zoom took
roughly a couple of weeks - the "Pinwheel2" image in my Mandelbrot Set

plodder & I usually run out of patience.  Maybe I can convince my wife
we really DO need that new PII-450...

Dear all,

What do people usually charge others for colour prints of their fractals?

What size is the most popular?

Anyone selling theirs for a living (and making it)?

Any other discussion on selling fractal prints welcome.

At least what it cost to print them (figure in any mileage, personal
time, etc...).

>
> What size is the most popular?

Depends on your audience/customers, and your pocket book.  You don't
want to create large expensive prints if nobody will be able to afford
them.  You could print them yourself at 1440 x 720 dpi using something
like Epson's Stylus Color 1520 for paper support up to 17" x 22" (13.6"
x 21.78" printable area) or their Stylus Color 3000 for 17" x 196"
banner paper.

>

There are several people making fairly regular sales from their fractals
in some form or other (whether prints, CDs, calendars, T-shirts, etc..) 
I don't think anyone is actually making a living at it though.  There
are some individuals that are making money from selling other's fractal
images for various design situations and/or from using them at their
website as "free graphics" with lots of commercial banners.

>
> Any other discussion on selling fractal prints welcome.

Best to get some idea of who all would actually be interested in buying
some of your prints, and how much they are willing to spend.

You can print them out and sell them at a flea market, as I've heard others
here have done.  I guess 5$US is reasonable, if they're on good paper, and
they look nice.

Both of the major browsers are serious security holes.  But at least
Netscape doesn't support ActiveX!

Just for reference, this is what I charge.  My prints are photographic,
rather than inkjet.

Size    Price
5x7    $10.00
8x10    25.00
11x14   50.00
16x20  100.00
24x30  250.00

> What size is the most popular?

That really does vary.  I would guess 11x14 is the most popular, but I've
sold many at 5x7 and am now awaiting an order for 1 30x40 and 1 40x40
print.

Not me.  I tried a couple of times and failed miserably.

I am very resistant to the idea of selling my prints at a flea market.  I
guess I have this attitude that my work is "art", and I won't be taken
seriously as an artist if I take root at a flea market.  So, I don't sell
much, but when I do, I get a good price.  I recommend that anyone who
feels like I do to make sure their prints are of high quality and to not
be afraid of asking for what they're worth.

I agree with you and others in that the key is to find a market.

I've browsed many of the artists who have web sites and see many
beautiful images.  However, my reaction is similar to my reaction to
photographers selling their images at art fairs, galleries, etc.  That
is, being a non-professional photographer, I just find it hard to bring
myself to buying images that I look at and think, "I should be able to
do that myself, so why pay for it?".  Now, chances are that with the
time and equipment, I might be able to come close.  In some cases, there
is no way that I could achieve their results.

The same with fractal images.  I've access to the same tools, in most
cases as the artists, so why can't I find equally beautiful images.
With enough pracice and learning I think I can come close.

I don't mean to diminish in any way the accomplishments of fractal
artists.  It's just that I'm not likely to buy images at this point.
Other artists provide me with a standard of excellece to stive for,
which at this point, seems like Mt. Everest.  :-)

Yeah, ActiveX is pretty dumb, but barely anyone other than MS uses it,
really :)  Of course, a few pages use it, but (almost) all the controls come
from MS's database thing.  It asks you when you want to download a new one,
too.  ActiveX's just MS's way of one-upping Netscape, after all...  I mean,
it's almost a game: Navigator -> IE, JavaScript -> VBScript, Java ->
ActiveX, etc etc.  But, then again, Netscape has paralleled MS a couple
times too.  ActiveX is IMHO just an instant-on plugin spec, pretty much.
There are lots of Netscape plugins that have been implemented as ActiveX
controls for IE.  So, if you just don't d/l any new ActiveX controls from
potentially unsafe sites, you're ok.  IE keeps all the ones you've gotten so
far on your computer, so you rarely need to do that, anyway.

The archiver I used (RAR) gives very good compression ratios (10:1!!), but
unfortunately, it's not widely used.  Not only that, but an archive created
with the most efficient compression can't be converted into a dos EXE (only
Win32 & os2).  So, either you need to get the RAR program for dos (and
extract it the way you would any other archive), or download the 2 megabyte
zip file that I'm going to be posting shortly.  (In comparison, the RAR
archive is about 600k.)  I've also made a smaller (pixel area-wise) version,
which is compressed using a standard video codec (at some loss of quality),
and is about 180k.  Both will be posted by 9:00am EST this morning.

As a newbie to real fractals, as I am beginning to realize comparing my
puny little fractals to some of yours , I have put up a page to display
some of those puny little ones. I have tried to inject my personality into
some of them by adding post processing with Paintshop Pro.
I am not new, however, at designing web pages. So I would ask that if you
have time to look at my pages for a good laugh, and maybe give me some feed
back. I am enjoying this list and have just learned how to use the .frm and
.par files from the list. It's exciting to learn some thing. If some of you
wonder about my title, It is from another website that I have, just trying
to tie together two different interests.

Maybe the right people to sell fractal prints to are the people who

This rather depends on your settings. I have all activex use/dl set to
disabled. I noticed though that some people have set their IE security such

You're never ok, but you can approx it by disabling activeX dl completely.

One note: if you have win98 and want to use 'Windows Update' or something, you
*will* need activex.

Yeah.. unless you keep reinstalling all the time... that's the problem always
with that Windows update, too: updates aren't stored on your harddrive for
later use.

I must say I've never seen a file archiver that does have such a good ratio as
RAR, but 10:1 surely isn't representative. It does little better that arj,
zip, jar, and a lot better than zoo, lzh etc, but that's all.
IF you're not compressing weakly-compressable binaries (exes and such). RAR
can then even enlarge the file. It is annoying that this cannot(?) be turned
off.
Also, RAR doesn't have as many options as ARJ has. But ok, who *uses* all ARJ
options? Although the more advanced, the nicer :-)

The DOS version of RAR is also user-friendly. It of course works in command
line mode, but also in a text-based full-screen interface. NOTE: the command
line version of RAR delivered with WinRAR does *not* support the dos screen
interface.

Also, RAR is terribly slow with it's solid archive implementation. I have RAR
files of over a 100 MBs, which take one or two eternities to be read, both by
the dos and windows versions. The dos version further rereads the archive
completely when you enter an archive's subdir from the screen interface. This
could take up to 15mins! The windows version stores the archive info a bit
better in memory; the archive is not to be completely reread after browsing
through intra-archival directories. And here we are only browsing through the
archive, not even doing anything useful like extracting or so.
And there's a thing you should NEVER do with rar files: delete a file from the
archive. This takes an eternity cause rar has a ridiculous method of keeping
the archive real solid.

Then, well, it *has* to be a coincidence (I hope!), but after burning a cd
containing a rar, the rar archives again and again have crc errors. We (me and
two fellow list-members) have this all the time with rar archives, and never
with zips, arjs, etc.

>> Not only that, but an archive created

Yeah.. with the win/os2 versions! The real dos version of rar DOES support dos
SFXs!

I really wonder what pre-set compression rate you used for (win)zip. The
difference in zip/rar is too much for zip to be at max compression.

I also have a rar-related question: what is RAR' url??? My rar documentations
mentions some hazy url http://www.thepoint.net/~jkracht  Couple of weeks ago I
checked, but i do not believe this url to be still active.

Kerry,
How and why
Do photographic prints last longer.  How do you get a developable
negative from a computer? Are you taking a photo of a printout.

Forom what I've seen at the art shows I've been involved with, only 2 things

Fifty+ years after World War II, there are still large groups of people who
"don't get" abstract art.

But I have to say, that I've only experienced positive feedback from the
public, both from those who know about fractals and those who know nothing
about them.  A wide range of people always asks me about my pictures wherever
I show them.

Now, if I can only get them to take the next step and part with their money...

------------
Could go on a titrate defending the "general public" or say do you really
think folks who buy pink plastic flamingo are  likely to be impresses
with a wonderful Gallet.
Just maybe, maybe, maybe, the general public (most People?) includes a
lot of creative folks who don't want to spend their creative energy
plugging numbers into a box.  We pay for art because it brings us
pleasure.  Because one has recordings of others music does not mean it is
"over the head" of the listener.   Often what we enjoy the most is what
inspires us the most and not necessarily in the same field.  Less is
"over the head" of the "general public" than the self proclaimed "elite"
often think.

No need to 'defend' the GP...  they've not been attacked. !!!

The "proclomation" is often the proclomation of the market not the artist. 
"Elete" [imho] is just a term that seperates one from self which is not my
preference...
But...when some one doesn't "see" what is there....it's all to obvious....but
it's also perfectly ok.
Every instance is different.

Photographic prints have better color, are cheaper, easier to reproduce,
last longer, get better gas mileage, pay their taxes on time, and have
better breath.  :-)

To get a photographic print, there are a couple of basic methods.  One is
to simply take a photograph of your monitor.  This works best when you
have a decent camera with a long (100mm focal length or so) lens, and a
tripod.  Turn out all of the lights in the room and use a fairly long
exposure (1/2 - 1 second) to blur together all the scan lines.  You'll
want to use slow speed film (100 ASA or slower), which also has finer
grain and makes better enlargements.  On the monitor side, 1024 x 768 is a
good minimum resolution; the higher the better.  Also, 24 bit is great if
you have it.  This technique gives you cheap, quick results which can
easily be enlarged to 8x10 prints.  When you make larger prints, the
pixelation shows up fairly clearly.  However, I've got some 16x20 prints I
made from 35mm negatives of a monitor that look pretty good.  It depends
on your taste and how much detail and contrast the image has.

The good, expensive way to do it, which I recommend for 16x20 and larger
prints, is to have a transparency made from your digital file, then have
that transparency printed by a good custom photo lab.  Several people on
the list have done this and an attest to the quality and cost of this
method.  Replicolor, out of Salt Lake City, can make a 4x5 transparency
for $75, or put 4 4x5's onto an 8x10 for $100.  I've had prints up to 40"
x 40" printed; the 40x40 ("27" from my web page) cost around $300.
However, it's an archival quality, professionally printed image, that will
knock your proverbial socks off.

Date: 08 Oct 1998 23:40:03 -0400

A belated note of thanks for those who sent comments about my images.   It was alot of fun
to participate, and certainly a nice ego-boost to get a few votes!   I've included the
parameters for the three images below, plus a couple of additional creatures that were
lurking about.

All the images are based on the generalized PopcornJul formula that I did a long while back.
My interest in this formula was re-kindled by some nice Popcornjul images posted to the list
some time before the contest.   I kind of became obsessed with it, and have saved almost a
hundred (!) PCJ images.   If anyone is interested, let me know and I'll send you the lot :-)

Here's how I make some of my photographic prints.

With a little effort and planning, you can use your camera to make quick,
colorful and relatively inexpensive prints of your fractals.  Photographic
prints, when properly done, are more vibrant than inkjet prints and have
an archival lifetime much longer than inkjet prints.  In this article,
I'll describe my technique for photographing the monitor and making
fractal photographs.

First, you need an image.  When creating your image, you should take full
advantage of your system's capabilities.  That is, you should create
images that use the highest pixel and color resolutions you can display.
For example, if you can display 1024 x 768 pixel, true color images, then
you might want to generate a 3072 x 2304 image and anti-alias it down to
1024 x 768.  You can do this with an image-processing program like
Photoshop or Picture Publisher.  You may also want to sharpen the image a
bit after resizing it.  Make sure that your image-processing program has a
"view full image" mode, in which the complete image is shown, without any
borders or window elements visible (you don't want those in your fractal
print).  If your image does not have 4:3 proportions, you may want to add
black borders around the edges.  This will help you keep the image
centered in the photo view.

Next, you need a camera.  It's best to use a 35mm SLR (single lens reflex,
or "through the lens" viewing) that lets you set the aperature and shutter
speed manually.  You'll need a long lens (focal length of 100mm or longer)
or a zoom lens, preferably with a macro setting.  This will allow you to
fill the viewfinder with the computer monitor.  The long lens will also
help flatten the image, reducing the effect of the curved screen.  You'll
need a tripod to steady the camera, and a cable release so you can release
the shutter without jarring the camera.  Set up the camera a few feet in
front of the monitor, taking care to make sure that the camera is square
with the monitor face.  Otherwise, you'll have some skewing and other
distortions in the final print.  Use the zoom on the lens, or move the
camera to fill the viewfinder with the monitor image.  To set the focus,
it may be helpful to toggle to a text screen, or to a screen with thin
vertical lines.  (I find it better to use manual focus rather than
autofocus, as some images can confuse the camera.)  It's important to use
an SLR camera, so you can set the focus with the exact same view that the
film will see.  "Point and shoot", or "rangefinder", cameras, have a
slight offset between the viewfinder and the lens.  At this close
distance, that offset can be critical.

To take the picture, make sure that there's no other light in the room.
Cover the windows and turn off any lamps.  Any other light in the room
will tend to wash out the monitor image and may cause reflections off of
the glass.  Once you have the image set in the viewfinder, you'll need to
set the aperature and the shutter speed to get an accurate exposure.
Although it may look like a static picture, you're actually photographing
a moving image.  Depending on your set up, the monitor is redrawing the
picture 50 to 100 times per second.  In between refreshes, the phosphors
in the monitor begin to fade.  If you use a short exposure (less than 1/30
of a second), you'll probably catch the monitor between refreshes.  You'll
see a dark horizontal band across the picture, where the phosphors are
fading and have not yet been refreshed.  To compensate for this effect,
use a long exposure (1/2 second to 1 second).  This will blur together all
the dark bands, giving a nice, bright picture.

The other setting that controls the exposure is the aperature.  This is
the size of the hole through which the light comes.  Normally, you use the
aperature to control the depth of field of the image, or how much of the
image is in focus.  However, if your image is completely taken up by the
monitor, then just about any aperature setting will have the entire screen
in focus.  Use the aperature (or f-stop) to control the light:  lower
numbers (f/4 or f/5.6) to allow a lot of light in, and larger numbers
(f/11 or f/16) to reduce the light.  Use your camera's meter to determine
the appropriate aperature setting.

I have found that strict adherence to the camera's metering leads to
overexposing.  Therefore, be prepared to take several exposures for each
image.  You should bracket your exposures, which means taking 2 or 3
pictures of the same image with different aperature settings.  For
example, if the meter indicated that you should use an aperature setting
of f/8 with a shutter speed of 1 second, then you might also want to use
settings of f/11, f/16, and maybe f/22.  This should ensure that you get
at least one exposure that you like.  In the long run, it's better to take
multiple exposures and only use one, than it is to go through this entire
process and not have any usable pictures.

The film you use is also important.  Color film (print or slide) is
classified by film speed (ASA or ISO number).  The higher the speed, the
faster the image will develop on the film.  The film accomplishes this by
using larger grains, the particles of emulsion that make up the picture.
When you have your images enlarged, fast film will give prints that look
"grainy".  To avoid this, use slower speed film, ASA 100 or slower.  This
is also necessary to allow you to use the slower shutter speeds needed to
avoid the dark bands.  For prints, I use Kodak Royal Gold 100 film.  Kodak
films tend to have a wider exposure lattitude, meaning that you can use
long exposure times before the fails to respond as expected.  However, I
find that this film has trouble accurately reproducing cyans.  Recently, I
started using Fujicolor Super HQ 100, and like it's colors better.  The
best way to compare films is to shoot the same series of images with each
film, have then developed and printed at the same lab, and compare the
prints.

Once you've shot your roll, you have to entrust it to a photo lab for
developing and printing.  Unfortunately, this step is critical to getting
good prints, and is one over which you have little control.  The
developing of the film is automated and usually goes well.  The printing
step is usually done by someone who may have a pretty good idea of what
people and landscapes should look like, but may have no idea how fractals
should look.  This is important because the printer has a lot of power in
determining the final color of the print.  Further complicating matters is
that you can never exactly match a print to what you see on the screen.
The screen image represents transmitted light, which is of a different
quality that the reflected light coming off of the print.  If you decide
to take a lot of pictures of your monitor, it will be important to find a
photo lab with whom you can work and who will take direction.  I use
one-hour labs, because I can give immediate feedback to the printer about
the colors.  The printer will generally have control over either the red,
green, and blue channels, or the cyan, magenta, and yellow channels.
Also, they usually have a "density" control; low density makes the image
too bright and washed out, while high density makes the colors very
vibrant and dark.  If possible, you should have a color guide to show the
printer how the colors should look.  If you have a good color printer, you
can print one or two images and give them to the printer to match.  Or,
you can create a "test pattern" of standard colors.  Have the printer
correct for the test pattern, and then print all of the other images the
same way.  When you get a good print of your image, use that as a color
guide when you have enlargements made.

While a bit involved, this technique provides a means of creating
photographic prints of your fractals.  When you master it, you can create
small- to mid-size enlargements quickly, easily, and with minimal expense.
Have fun with it--I have.

 (Snipped...)

If I may interject - 

I used my Canon AE1 to do pretty much as Kerry described once for a couple
of images, and took them to a photo shop (Tech Lab). The prints were fine.
The reaction of the people at Tech Lab was ... different. They really liked
the images and when I walked in to pick up the prints they wanted to
discuss briefly what I was doing. They had not seen these kind of
photographs...

Tech Lab has capabilities to reproduce and print images from floppy disks
and they asked if I would like to try that. I brought in a floppy and they
ushered me into the back where I could watch what they were doing; they had
some nice equipment.

In turn I also printed out some images on my Epson 800 color stylus. On
this list we had a brief discussion sometime ago concerning print quality
and paper types to use.

The upshot was that I found using Kodak photo film paper stock with a dpi
of 1440 gave images that were comparable to what the photo lab was giving
me. However, the ink seemed to water soluble and required spraying with
krylon or other sealer. I think it was Jack Valero who mentioned that Epson
paper absorbed the ink better and the image would not be water soluble. 

I had purchased one package of Epson photo paper (at the time I had not
tried it), one of Kodak film quality paper, and one of HP photo quality
paper. The Epson paper was not photo film quality type.

The Epson paper indeed did absorb the ink better and as a result the ink
was not water soluble in effect. However, the image did not compare to the
quality obtained using both the Kodak and HP photo film stock; this was due
to the Epson paper having a matte finish as opposed to the gloss finish the
film stock has. Accordingly I would stay with the Kodak and/or HP stock and
take the extra step of spraying the image lightly.

Above fwiw....

There is another method that, IMO, would be far superior to
photographing one's monitor, but not as costly as your method here.

That is to use one of the digital print services such as Sedona DPS,
http://www.sedonadps.com, or Boston Photo, http://www.bostonphoto.com .

I've used Sedona several times.  You can get an 8x10 print made from a
digital file for about $8.00, and additional ones are less.  This isn't
any more expensive than photographing a roll of your monitor,
processing, printing, then enlarging what you want.  Plus, the quality
will be much higher.

The main disadvantage to Sedona is that they use JPEG compression on the
images when you package them for uploading to be printed.  For my
purposes thus far, this hasn't been a problem.  I have not used Boston
Photo, but have heard good things about them.

One thing to keep in mind that I've learned from experience and
research, is that you really need about 200 DPI of image data to get a
good quality ink jet print or photograph made from a digital file.  A
monitor just can't deliver that kind of detail, and photographic prints
can't give you much more than that.  I generally use an image of
1600x2000 for printing an 8x10 image.  This has always yielded good
results for me.

If you are going for a transparency from your image, then you may want
a higher DPI, since the transparency is capable of recording more data.  
Maybe Kerry has some insight into what resolution produces the best
result when going from digital to transparency.

I would add that if you want to make photographs of your images from
your monitor, I would strongly advise using slide film.  The major
advantage being that by using a transparency film, you remove the human
element from determining what the colors should be.  The slide will
capture the image, using the characteristics of the particular film,
exactly as it exists on the screen.  You then have a positive image.

With negatives, the printer has to evaluate the negative and make the
appropriate color corrections.  A printer, will probably never have seen
a fractal before and likely have no idea what the colors should be.
Therefore, major guesswork enters into the picture.

If you want to shoot negatives, I'd suggest exposing a couple of frames
at the beginning of the roll of a know subject, people, scenery, or
ideally a color chart.  That way, the printer has a reference point from
which to make color adjustments that should apply to the rest of the
roll.

I agree.  Particularly when you view the slides--it is more like seeing
your images on a monitor.

Doesn't this also happen with printing from slides?  Doesn't the printer
have the same latitude that they have when printing from negatives?  It's
been my experience that printing from negatives can work out well, it's
just a matter of getting the (human) printer "calibrated".  Also, unless
you're doing Ilfochrome prints, prints from slides are done using
"internegatives"--that is, a negative is made from the slide, and that
negative is printed.  This introduces another optical element into the
process, reducing sharpness, and also re-introduces the color accuracy
problem.

Ken,

I agree with you in principle, but I think that you can still make good
enlargements from monitor shots, depending on your equipment, image, and
standards.  Current 17" monitors deliver 1600 x 1200 resolutions, and a
good video card and shoot that in true color, elminating any jpeg
artifacts.  Also, actual dpi numbers lose relevance when you're talking
about putting a picture on the wall where people generally don't get their
noses into it.  Of course, you're right about making big and/or detailed
enlargements--you just can't do that from a monitor shot.

Any service bureau that uses a Kodak LVT machine to make transparencies
from digital files will be able to write at least 80 pixels per
millimeter, and maybe 120.  That means about 2000 or 3000 pixels per inch.
On a 4x5 transparency, that's 8000 x 10,000 or 12,000 x 15,000 pixels.
Replicolor suggests going to an 8x10 trans at 80 ppmm rather than push a
4x5 to 120ppmm.

At these resolutions, file sizes are absolutely huge.  To compute the file
size, multiply the horizontal number of pixels by the vertical number of
pixels by 3 bytes/pixel.  (Service bureaus don't typically like to work
with compressed files.)  To fill a 4x5 trans at 2000 ppi, you're
looking at 240 million bytes of space, or just over 1/3 of a cd.  I
created one image the filled an entire cd, and I believe that it was
14,700 pixels on a side.  I had an 8x10 trans made of the file, and
printed the image out to 40" x 40", which is just over 360 dpi.
Definitely not a screen shot.  :-)

To print from transparencies like this, you should find a lab that does
Ilfochrome processing (used to be called, "Cibachrome").  It's a process
that prints directly from the trans, without an internegative.  There is a
bunch of other reasons why it's good (like color saturation and archival
life), but the main one is the "wow" factor.  Expensive, but definitely
worth it.

It can, but the major difference is that you have the positive image,
the slide, as reference to judge the final print from.  With a negative,
you have no positive image for the printer to use as a reference point.

There is another process that is positive to positve, other than
Ilfochrome.  Type R maybe, I forget.  I just had some make a little
while back.

However, you are correct in that if you have to go from a slide to an
internegative to a print, you are introducing another generation into
the process.  The advantage still being that you have the positive image
on the slide as a reference point.

An example from my personal experience.  I take underwater photographs.
As you descend, you rapidly lose perception of colors due to the
filtering effects of water.  Thus, when you are at 60 feet, you don't
know if that black thing you are looking at is black, blue, bright red,
or whatever.  When I got my slides back, I saw that that black thing was
really a bright red sponge.  I couldn't see what the color really was
and I wouldn't have been able to tell a printer to print that red from a
negative if the machine's color balance was all off.  The same exact
situation exists with fractal images as far as the printing process is
concerned.  The advantage is that you know what the image should look
like.

All methods discussed will work.  The particular individual has to
weigh the factors such as cost, image quality, ease, etc. to decide what
works best for them.  My preference is to eliminate as human error as I
can that is out of my control for what I do.  The best way I know to do
that is to use slides for photographs for underwater photographs, and
go from digital to a print for digital images.

I don't mean to say that this isn't a method worth consideration.  It
just isn't worth the effort for me because I can get better results for
less effort.  If you like the results, by all means use it.

This is true.  Which is why religious arguments about Epson vs. HP vs.
Canon printers are a waste of time.  Bigger enlargements can suffer less
DPI since you are viewing them from farther away.  However, you can't
take a 1600x1200 pixel image and get a very good 30" by 40" print from
it, IMO.

I agree completely here.  If anyone hasn't seen an Ilfochrome print, you
should make an effort to see the results.  They can be absolutely
stunning.  With the brilliant colors in so many of the fractal images,
an Ilfochrome print would be dazzling.  Definitely worth it, plus the
image will last for a long, long time.

WOW!!!  I have arrived.  :-)

I made one of the thumbnail images on Les's page.

Thanks Les, I'm truly honored.

Hi Steve - and all of you other great people outthere,

>I would LOVE....I say again LOVE...to hear a detailes description of the
whole
>process....starting with "This is the size I render to print a ??X??
photo."


I've been doing some 15"x10" digital prints (A3 paper). Many a photo shop
provides such prints, usually made on a digital color photocopying machine,
that can print as well. The machine my local printshop uses, prints at 400
dpi allowing lots of detail. The colors are vivid and clear, I'm very
satisfied with the results. Still, intense colors seems to do best, while
more pale or dusty colors have a lesser "wow-factor".

A print cost some 5 $ (30 danish kroner), but if you want multible prints of
the same picture, the price can be reduced greatly, even halfed. The method
is easy, all you need is fractint, a disk and maybe a photoeditor, and you
can make impressive posters.

In need of a portable harddisk or the like, I usually stick to 100 dpi
prints, since it allows me to have the file on a standard floppy disk. I
render a picture on 4500x3000 or 6000x4000 and then reduces it to 1500x1000
to anti-alias it. Then I use the photoeditor to specify the wanted size
(15"x10") and resolution (100 dpi), and the saves the ready-to-print file as
jpeg (with lowest compression, unlike gif jpeg allows the specification of
parameters such as size and resolution). Some photoeditors allows all this
to be done in one process. Notice that I use a resolution that is dividable
with the printers resolution (100 = 400 / 4). If I did not, it would
generate aliasing while printing - and it's nicer to avoid.

Kind regards, Kim.

Subject: (fractint) 5 point star coloring methods
Date: 09 Oct 1998 13:19:48 -0700 (MST)

Fresh from the, "Just because you can doesn't mean that you should" files,
:-) here are some formulas built around 5 point stars

Kerry Mitchell
lkmitch@primenet.com    www.primenet.com/~lkmitch/

comment { ; narrative copyright Kerry Mitchell 09oct98

Seeing Stars

Most fractal images involve circles in some respect:  either stopping
the iteration when the orbit moves outside of a given circle, or
coloring by how close the orbit comes to a certain circle, or some
variation.  These formulas use a 5 point star instead of a circle.
The "starnear" formulas color by how close the orbit comes to a star.
The "starbail" formulas are set up to stop iterating either when the
orbit comes into a star or when it leaves a star.

The star is represented by the 5 outer points.  These are equally spaced
on a circle.  The center and size of the circle are user-specified, as
is the rotation angle of the star.

How z at any iteration relates to the star (inside, outside, how close)
is determined by looking at each of the 10 sides, one at a time.  Each
side can be represented by a line A*x + B*y + C = 0, where A, B, and C
come from the coordinates of the 2 outer points that are joined to make
the side.  Given the numbers A, B, and C, the quantity

        q = A*real(z) + B*imag(z) + C

is computed.  If q is positive, then z is on one side of the line, and
if q is negative, then z is on the other side of the line.  If |q| is
very small, that means that z is very close to that side of the star.
Taking the signs of q for all 10 sides will determine if z is inside or
outside of the star.  Using the smallest value of |q| gives the distance
from z to the star.

To see this in action, use the formula "star".  It will draw the outline
of a star, with the position, orientation and size that you choose.
This formula, and the "starnear" formulas that are built on it, use a
logarithmic transfer function from distance to angle (for decomposition
coloring in Fractint).  This helps highlight the star without needing to
find out if the point is exactly on the star or not.  The "star-inout"
formula will draw a star in 2 colors.  Everything inside the star is one
color, and everything outside of the star is the other color.  These 2
formulas are simply to give an idea of how the method works.

The fractal formulas need a bit of extra explanation.  In the
"starnear_jul" formula, you have the option of whether or not to check
the pixel (initial value of z) for its distance from the star.  If the
star is centered at the origin (p2=0/0), this can make quite a difference.
For example, use the "starnear2" parameter set.  As written, the real
part of p3 is -0.28. The magnitude of real(p3) is the radius of the circle
containing the 5 outer points.  If real(p3) is negative, that tells the
formula to check the pixel for its distance before iterating.  In the
image, this shows up as a star in the center.  Now, make real(p3) +0.28.
You'll see that the outer portion of the image is unchanged, but the star
in the middle has gone away.  In the "starbail" formulas, the flag to
check the pixel before iterating (pixelflag) has been set in the formula,
and is not interactively changeable (too many parameters).

The "starnear" formulas use a standard bailout condition--stop when the
iterate gets too big, or leaves a very large circle.  Conversely, in the
"starbail" formulas, the bailout condition is built around a star.  If 
the star is centered at the origin and is big enough, then you can
essentially use the star instead of the traditional bailout circle.  This
is what has been done in parameter set "starbail1".  The magnification
was decreased to show the bailout star, and the fractal can clearly be
seen in the middle.  It is also possible to bailout when the orbit enters
a star.  This is similar to the orbit trap methods that others have
written, and works particularly well for Julia sets that are dusts.  An
example of this is in parameter set "starbail2".  Some care must be taken
if the star is not centered on the origin.  The "starbail" formulas set
z to a default (1,0) if the orbit was not caught by a star.  If the star
is too far away or too small to catch many orbits, the majority of the
screen will be one color (color 0 when using decomposition coloring).  If
you use stars off of the origin, you may want to increase the size and
set "pixelflag=0" in the formula, to prevent the image from being taken
over by one huge rogue star.

One final note:  This method uses angles a lot to figure out which side
belongs to whom.  Consequently, the ability to rotate the star is a bit
limited.  If the rotations are kept to the range of 0 to 36 degrees, there
shouldn't be any problems.  Rotations outside this range (try it with the
"star" formula) will result in branch cuts as the formula gets its angles
confused.  Fortunately, since the star is symmetric, there shouldn't be
a need to rotate it beyond those bounds.

Hi there...

Which brings to mind the digital camera.

My brother is bringing it over tonight.
It produces jpg and he claims that to get prints on paper all one needs to do
is deliver them to the right service agency.
Appearently the files aren't huge as he sent me a few shots of the of the
mountains last week while on vacation. They seemed to be at
1280x768...downloaded fast
and looked very very good!

Hi Kim

Have i missed a fractint up-date???  The highest videomode I have
[in 19.6.... disk ram ] is 2048x2048 or 2048x1536.
How are you getting 4500x3000 and 6000x4000?

Fractint still generates images at 2048x2048, but if you want higher
resolution images for printing quality prints, then use Fractint's
"pieces" divide-and-conquer feature.  You can create multiple PAR
entries that break an image up into pieces so that you can generate the
image pieces one by one.  There are two reasons for doing this.  The
first is in case the fractal is very slow, and you want to generate
parts of the image at the same time on several computers.  The second is
that you might want to make an image greater than 2048x2048.  The 
parameters for this feature are:
    X Multiples - How many divisions of final image in the x direction
    Y Multiples - How many divisions of final image in the y direction
    Video mode  - Fractint video mode for each piece (e.g. "F3")

The last item defaults to the current video mode.  If either X Multiples
or Y Multiples are greater than 1, then multiple numbered PAR entries
for the pieces are added to the PAR file, and a MAKEMIG.BAT file is
created that builds all of the component pieces and then stitches them
together into a "multi-image" GIF.  The current limitations of the
"divide and conquer" algorithm are 36 or fewer X and Y multiples (so you
are limited to "only" 36x36=1296 component images), and a final
resolution limit in both the X and Y directions of 65,535 (a limitation
of "only" four billion pixels or so).

The final image generated by MAKEMIG is a "multi-image" GIF file called
FRACTMIG.GIF.  In case you have other software that can't handle
multi-image GIF files, MAKEMIG includes a final (but commented out) call
to SIMPLGIF, a companion program that reads a GIF file that may contain
little tricks like multiple images and creates a simple GIF from it. 
Fair warning: SIMPLGIF needs room to build a composite image while it
works, and it does that using a temporary disk file equal to the size of
the final image - and a 64Kx64K GIF image requires a 4GB temporary disk
file!

I don't want to start a digital vs. film war, so I'll just make one
comment.  For a great many uses, digital cameras are a great tool.  For
my uses, only the $10000+ cameras can approach the quality I want in
digital.

  Simplgif also has some serious bugs that made it fail on about half of

Hmmm, I thought we had gotten the bugs out of simplgif. Were you using the 
version with the new decoder/encoder (I would think you were, since you keep 
up pretty well.)

I'd be interested in an example that breaks it, though it might be hard for me to 
handle the disk space.

Well, obviously you should have!
Your latest formula has lots of potential, but that's what we've
come to expect.  You're spoiling us, Kerry!  :-)))

If they weren't so hideously underpaid, you should have been a

Sorry, man.  I think it's been two or three years since 
I read your bio data.

And of course I meant *formulae*, not formula.

  These are totally great.  The classic Mandelbrot
bailout is a circle but it doesn't mean the image has
circles in it.  I don't know why this one actually has
stars in it but it's beautiful and I have to make some time
to look at this further.

Hey fractineers out there. Just some inside information for all.
There is a space filler virus on the loose that does some weird stuff.

A lot of people are infected and don't even know it yet. It's name is
"Win95 CIH spacefiller". Please search for it on the Net and find out how 
to get rid of it if you have it and prevent it from infecting your system.

At the end of each month I par-to-bat the whole collection at 1600x1200 and make
a set of thumbnails too (to check that the the par file has no bugs). I then
have my own "mini contest" where I pick my favourite three images to display on

narrow it down to just three favourites!

Afternoon, folks...

I should know better than to post new formulas late at night.  I really
should.  :-)  The triangle-inequality Julia formulas I posted last night
are not quite correct.  They will produce images which are interesting, but
are slightly incorrect.  The two formulas below are the correct versions; I
have named them differently so that if you have already used last night's
formulas, you will still be able to reproduce them.

Subject: (fractint) Boundary tracing
Date: 10 Oct 1998 19:48:17 +0100

I've been doing some zooms where I found it relevant to use boundary tracing
as drawing method. It made me wonder if it could be improved in the
following way:

Instead of doing the left-to-right calculation as "primary search", I think
it could be neat to do a rectangular search. That is left-to-right at the
top, then down along the right border, then right-to-left at the bottum,
then closing the rectangle by doing the left border upwards.

This would (at least for the mandelbrots I just did) fill all the larger
areas first, and thus it would appaer to draw quicker - whether it acctually
would, I don't know, but I got a hunch, that it would.

Any comments?

Kind regards, Kim :-)

I have just updated Truemand with some enhancements to the orbit trapping 
methods and some bug fixes. The new fractal of the week was created using 
the new orbit trapping methods. Some additional new images using the 
methods are in True Color Gallery 2.
Truemand is free, creates 24 bit images, and uses fractint color maps. It 
can also use fractint formula files with some minor modifications. If you 
have a laptop with only 256 colors, it will generate a "true color" image 
with no banding using the Stuckii error diffusion algrorithm.

This is a very important point. We completely redid both the GIF reading and 
writing of Simplgif. I believe the one at my FTP site is the new one. It is at

ftp://ftp.phoenix.net/pub/USERS/twegner/simplgif.zip

I really want to know if this version has any bugs. I haven't heard of any bad 
cases with the new simplgif.

  I tried again with the Simplgif that is at your ftp site and found two
images that show the bug.  Both were made of 4x4 1024x768 pieces and in
both cases, the first line of the resulting simplgif.gif is incorrect. =

Would you like me to put them on a CD ROM for you?

    //
    // I must say I've never seen a file archiver that does have
    // such a good ratio as
    // RAR, but 10:1 surely isn't representative. It does little
    // better that arj,
    // zip, jar, and a lot better than zoo, lzh etc, but that's all.
    // IF you're not compressing weakly-compressable binaries (exes
    // and such). RAR
    // can then even enlarge the file. It is annoying that this
    // cannot(?) be turned
    // off.

You're right, it isn't representative, but with RAR's Multimedia setting, it
works about twice as well as normal (i.e. avg. 4:1 vs. 2:1).  RAR probably
enlarges the file because it has a very large header, but I'm not sure.

    // Also, RAR doesn't have as many options as ARJ has. But ok,
    // who *uses* all ARJ
    // options? Although the more advanced, the nicer :-)
    //
    // The DOS version of RAR is also user-friendly. It of course
    // works in command
    // line mode, but also in a text-based full-screen interface.
    // NOTE: the command
    // line version of RAR delivered with WinRAR does *not* support
    // the dos screen
    // interface.
    //
    // Also, RAR is terribly slow with it's solid archive
    // implementation. I have RAR
    // files of over a 100 MBs, which take one or two eternities to
    // be read, both by
    // the dos and windows versions. The dos version further
    // rereads the archive
    // completely when you enter an archive's subdir from the
    // screen interface. This
    // could take up to 15mins! The windows version stores the
    // archive info a bit
    // better in memory; the archive is not to be completely reread
    // after browsing
    // through intra-archival directories. And here we are only
    // browsing through the
    // archive, not even doing anything useful like extracting or so.
    // And there's a thing you should NEVER do with rar files:
    // delete a file from the
    // archive. This takes an eternity cause rar has a ridiculous
    // method of keeping
    // the archive real solid.

When RAR creates a solid archive, it treates all the files as a single file,
rather than restarting the compression (i.e. recreating the dictionary,
etc.) for each file.  I compressed the set of PNG files (which already have
good compression ratios) for that animation, and got *2:1* compression on
them, even though their already compressed!

    //
    // Then, well, it *has* to be a coincidence (I hope!), but
    // after burning a cd
    // containing a rar, the rar archives again and again have crc
    // errors. We (me and
    // two fellow list-members) have this all the time with rar
    // archives, and never
    // with zips, arjs, etc.
    //

I'm not sure about this, you may want to email the author.

    // >> Not only that, but an archive created
    // >> with the most efficient compression can't be converted
    // into a dos EXE (only
    //
    // >> Win32 & os2).
    //
    // Yeah.. with the win/os2 versions! The real dos version of
    // rar DOES support dos
    // SFXs!
    //

Well, I haven't used the real dos version, but I may have to.  With the
version included with WinRAR, you can't create an SFX out of a RAR created
using a 1024K dictionary, unfortunately.  All the files give you CRC errors
when decompressed.

    // >> So, either you need to get the RAR program for dos (and
    // >> extract it the way you would any other archive), or
    // download the 2 megabyte

    //
    // I really wonder what pre-set compression rate you used for
    // (win)zip. The
    // difference in zip/rar is too much for zip to be at max compression.

Max compression.  I got about 4 times that with RAR using multimedia
compression.

    //
    // I also have a rar-related question: what is RAR' url??? My
    // rar documentations
    // mentions some hazy url http://www.thepoint.net/~jkracht

I think www.rar.com is right..

Steve,
I am using Photoshop 4.0, but 5.0 should be the same. Select "preferences" 
on the file menu, and then "general". There should be an drop down box for 
"interpolation". Select bicubic.  Whenever you reduce the size of an image, 
Photoshop will apply bicubic interpolation ("anti-alaising") to the image. 
I usually do a 2.5 - 3 fold reduction to get good anti-alaising. I can't 
tell you right off hand what the mathematical details are, I just know its 
one of the most accurate methods for image reduction.

To use a similar "bi-cubic" in JASC's Paint Shop Pro 5.0, you need to
use the menu selection of IMAGE | RESIZE...  Then within the pop-up
window there is a drop-down list for Resize Type, one of the options is
for "Bicubic resample" (another is Bilinear).

Bilinear and Bicubic Resampling Methods

The Bicubic Resampling method of resizing minimizes the raggedness
normally associated with expanding an image by using a process called
interpolation. As applied here, interpolation smoothes out rough spots
by estimating how the "missing" pixels should appear, and then filling
them with the appropriate color. It produces better results than the
Pixel Resize method with photo-realistic images and with images that are
irregular or complex. Use the Bilinear Resampling method for shrinking
these images and Bicubic for enlarging them.

Bilinear and Bicubic resampling are available for grey scale images and
24-bit images.

If the image does not fit these categories, and you would like to use
one of these methods, do the following:
    1.  Increase the image’s color depth.
    2.  Resize the image.
    3.  Reduce the image’s color depth and return it
        to the original depth.
Further information on "increasing" and "reducing" will be found in
PSP's Help file.

Hmm. I think it's time to check out WINRar soon... I'll try multimedia compression. May be
useful - I'm always running out of disk space.

No. It would seem so right. I in fact tried this url first; and when it didn't work, i
browsed through the documentation, where i found the thepoint url.
I just checked out www.winrar.com  www.rar.org  www.winrar.org  www.rar.net  and
www.winrar.net
but none of these actually work.

 To use a similar "bi-cubic" in JASC's Paint Shop Pro 5.0, you need to
 use the menu selection of IMAGE | RESIZE...  Then within the pop-up
 window there is a drop-down list for Resize Type, one of the options is
 for "Bicubic resample" (another is Bilinear). >>

Ron and Paul...Thank you!

Pixel resize, bilinear, and bicubic interpolations actually form a series
of related interpolation methods. All involve fitting curves to points.
A fourth, "biquadratic", which is virtually never used, also belongs to
this family, and fits in between bilinear and bicubic. The family continues
with "biquartic", "biquintic", etc.

Every second interpolation method (starting with "biconstant" or pixel
resize, and biquadratic) has the problem of sharp edges appearing between
blocks of pixels that give away its enlarged nature. This is why
biquadratic interpolation isn't used.

All use the values of a certain-sized neighbourhood of pixels in the
original image to guess what the interpolated pixels in the enlarged image
should be. The difference is in the size of the neighbourhood.

With one pixel, the method takes the colour of that pixel and copies it
throughout its neighbourhood. This is constant, or "pixel resize"
interpolation.

   *--
*--   *--

With two pixels, we can draw imagine drawing a straight line between them
and colouring it with a smooth gradient from one pixel's colour to the
other. So one quarter of the way from a red pixel to a blue pixel would be
"three-quarters red, one-quarter blue"; and half way we'd find a
medium-dark magenta. This is linear interpolation.

   *
  / \
 /   \
*     *

With three pixels, we have enough information to draw a quadratic curve
from the first pixel through the second to the third. The section between
the first and second pixels is then coloured to fit this curve. If the
third pixel is higher than the second:

     *
    /
   *
  /
*-  the interpolated pixels are generally closer in colour to the first
pixel, and only toward the end do they drift up to match the second. If, on
the other hand, the third pixel is _lower_ than the second:

  -*-
 /   \
*     *  The interpolated pixels between the first and second pixels will
tend to be more like the second pixel in colour.


Cubic interpolation is next. This takes _four_ pixels to define a cubic
curve. The section that actually gets filled in is the part between the
second and third pixels. This means that not only is the shape of the curve
affected by where it's going, but where it has come from as well. This
avoids the sharp edges that appear in constant and quadratic interpolation.
      -*-
     /   \
  -*-     *
 /
*

Now that we have a way of interpolating colours between two pixels in a
line, we need to extend it to two dimensions. How does one go from cubic
interpolation to bicubic? In this situation we end up with little
rectangles that need to be coloured in, instead of little line segments.

* * * Do all the vertical edges with cubic interpolation, and
| | | then fill in the spaces between horizontally using cubic interpolation
* * * again.
| | |
* * *

Pure drivel, but there might something in it.

Thanks for posting those.  I made these last month-

      Also, they nearly but don't quite have y-axis

I thought this was about image resize to *REDUCE* the size of the image.
You are all describing increasing the size, which is the only situation
where your "missing pixels" logic would come into play.  I would like to
understand what bearing this has on anti-aliasing.

And there is a sense of accomplishment if you find something unique and
acceptable by the "general public". The trick is to show your works to an
audience who is interested and financial which I do not believe are the
creators - they are usually poor;-) It is usually over the head because they
don't have the inclination to try to understand, nor do they want to.

wouldn't finish it, maybe its geocities, maybe the pics are too big

I did a search for "WIN95 CIH spacefiller" and got a list of results such
as:
C:\WINDOWS\OTIONS\CABS\Win95_28.cab
I suspect they are nothing to do with the virus as they are dated '97. Am I
right or wrong. I've never had a virus(touch wood). Are these files anything
useful? I've only ever downloaded fractal stuff, is the source of the virus
known? Warnings like this are only useful to the group if there is enough
info in the first place to find/destroy the virus easily, otherwise it can
create a flood bigger than the mississippi on unrelated topics. I for one
don't know where to search/ how to start looking for viruses, win95 takes up
enough time with all the "virus-like" bugs in it. Direct links to how to
destroy the virus etc would be useful. Or a list of files  which carry the
virus etc. Otherwise info like this tends to be ignored....

This "might" be because you didn't empty your browser cache after uploading
the 
page. It "might" be reading the files from your local drive instead of
geosites.
Emptying your browser cache before final appraisal of your site could be a
good idea
to avoid allowing your browser to load info. from local drive when your
objective is to see it load from your servers drive.

Also thanks to Joe Weber for the chance to see the same[his site and available

Well, all those cab files aren't really nessecary.  If you have the original
Win95 CD (if you don't, well, wink-wink <g>)  and you are running out of
space, you can delete them all.  There just there if you want to install
more Windows components, or if you need to install new drivers.  They aren't
nessecary for the day to day operation of Windows.  (You can really just
delete the whole Cabs directory.)

Well, well, It went faster than I thought: It is as well as ready, only

Ups!

Still, it works fine when I try, so I'm pretty confused.

It should be basic HTML, using frames as the only "fancy" detail. I use
MSIE, could this be a IE / netscape thing? Suggestings are more than welcome
off the list!

You have several HTML errors on many of your webpages and files.

On your "main" page, you have:  >/NOFRAMES>  where the first character
is reversed.  You also have the BODY tag specified on a FRAMESET file
which is not allowed, so try the following:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">

<NOFRAMES>
This page uses frames, but your browser doesn't support them..."
</NOFRAMES>
</FRAMESET>
</HTML>


On your "fracmenu.html" file you have the following code:
    <A HREF="..\tour\tour.html" TARGET="THESITE">
You may wish to reverse the direction of the "slash".

A good test of HTML if to flush your caches (temporary internet folders
etc) and then dial up to your own site and view it on-line. That way, it
won't pull up a picture still contained locally from your development
time.

I see many sites with broken links and mising pics due to the fact that
they've been tested on the same machine that's developed them and as
such is viewing stuff stored locally, not stored on the ISP's server.
Viewing the source code shows that the link to the pic is "C:\Program
Files\Office\ClipArt" etc...

Your tour page lists links with back slashes instead of slashes. I was
viewing the source of your files and finding the name of the next link.
That got a bit too cumbersome before I got to any of the pictures.

You need to put the frames stuff inside the body tags. And body tags are
required.

That should help a lot :)

It's probably an IE / standards thing.  Basic Web Standards primer:

1. There are a lot of browsers out there.  There are at least a hundred
versions of Netscape, because it runs on a dozen platforms and has been
through ten or so versions.  There are a couple dozen other browsers
that are used by some segment of the population, often outputting on
devices like text-mode terminals, palmtop computers with 160x100
screens, telephone receivers (really!  You can browse the Web over
the telephone.), screen readers, Braille terminals, etc. etc. etc.

2. You want these people to be able to read your web pages.  (Right?)

3. There have *always* been a lot of browsers.  There have never been
fewer than two major browsers.  

4. As a result, since the early days of the Web, there have been
Standards.  The Standards usually describe stuff you can do so that
nearly every web browser can understand you.  (The major exception is
HTML 3.0, which was full of garbage, so nobody implemented it.)  The
Standards are available from w3.org.

5. The standards are not sufficient, though.  No standard will tell you
why using frames is evil (see http://www.useit.com/alertbox/9612.html
for that) or why using cute little animated .gifs to spice up your
pages will make people go elsewhere (hint: a 100K .gif takes more than
a minute to download at 14.4kbps --- it'd better be worth the wait!) or
why using .BMP files for your images is dumb (hint: count the number of
browsers that support it) or why you should use client-side imagemaps
as well as server-side imagemaps or why you should not ever have a
three-page "tunnel" that leads to your actual useful pages.

For that, you could do the following:
	- look at www.suck.com
	- look at http://photo.net/wtr/
	- read www.useit.com
	- install a lot of web browsers, especially old ones, and try
	  out how they deal with your fancy tricks
	- validate your HTML so you can find things that work on your browser,
	  but don't fit the standard.

My web pages suck, though, so be careful about listening to me.  :)

Not for loading image files. That's so basic all of them do it the same way. 
It's either there or it isn't.
Empty your cache after every upload!!!!!!!!

Every compression program will sometimes enlarge the file.  There's a
mathematical proof of this, which I don't feel like explaining at the
moment, but will explain to whoever asks.  At the very least, you need
to add a byte or so to the beginning to indicate "this file has not
been compressed" --- otherwise, you have to try to decompress it, and
then ask the user "is this right?"

btw, bzip2 has usually about 20% better compression than zip, arj,
gzip, etc.  I wonder if it uses the same methods as RAR?  It's also
very slow.

This is incorrect!!  You should not include any <BODY> content within
the frame document; Netscape will ignore the frame tags and display just
the contents of a <BODY> tag it it comes first, or vice versa.  Use the
<FRAMESET> tag in lieu of a <BODY> tag in the frame document.  You may
not include any other content except valid <HEAD> and <FRAMESET> content
in a frame document, or the Netscape browser will ignore the frame HTML
tags.

Structure of a frameset document

The frameset document, which contains the <FRAMESET> element(s) used to
set up the frameset, differs from a normal HTML 3.2 document in one
aspect: it does not have a BODY section.  The <FRAMESET> element
replaces <BODY>.  The <HEAD> section of the document is still according
to HTML 3.2 rules.  The following is an example of a very simple
frameset, that consists only of two equally-sized rows.  The upper row
is named "foo", and the lower row is named "bar".  

<HTML>
<HEAD>
<TITLE>A sample frameset document</TITLE>
</HEAD>
<FRAMESET ROWS="*,*">
<FRAME SRC="foo.html" NAME=foo>
<FRAME SRC="bar.html" NAME=bar>
<NOFRAMES>
 <BODY>
 Any comments about what to do for other browsers uncapable.
 </BODY>
</NOFRAMES>
</FRAMESET>
</HTML>

Note that the <NOFRAMES> section of the document contains a <BODY>
element.  This is the only exception to the <BODY> tag rule, it is used
*ONLY* within the <NOFRAME> tag.  This can be used to include an entire
document, so that if support for frames is disabled, or not present at
all, the viewer gets alternative content.  But the comments could just
as well be added in the <NOFRAMES> section without any <BODY> element.

For the W3C HTML Validation Service, try the following URL:

Because of ridiculous and criminal US patent legislation, it's illegal
to make .gifs or write software that makes .gifs without paying Unisys
a licensing fee.  So most new non-proprietary software doesn't support
.gif.

The standard method for distributing compressed archives in the Unix
world is to first create a big file containing all the files you want
to archive with "tar", which doesn't do any compression, and then
compress the whole thing with "compress" or "gzip".  This has the same
advantage you describe above.

Thanks to you all for your kind interest in my site, I really appreciate it!

I have tried out all your advise:

- Emptying my browser cache made no difference for me: the site still loaded
ok from my web-hotel.

- I did some minor corrections on HTML - maybe most important I found an
extra " (quotemark) in index.html, that might have hidden the end-tags...
(my browser didn't care)

- Someone suggested putting frames-stuff inside <body> tags, but that gave
me a blank page! Hmm!

Having tested it to the best of my ability, I'd say it works...
(If not, I'll redo the whole thing without frames.)

Please look by again and feel free to complaint if it doesn't load!

Some examples: Infoseek and Netscape both had frame-based home pages
shortly after the introduction of frames.  Neither now does.  (This
bears repeating:  Netscape, the *inventor* of frames, doesn't use them
now!)

Some reasons why frames are not so good can easily be found at
www.useit.com, www.websitesthatsuck.com, www.suck.com, and
www.webreview.com.

Tried the site - I get the pics fine. 

I'm using MS-Incompetant Explorer 3.00 (probably 3.02 since I can see
frames) under NT4 workstation.

Guess the removal of the quote did the trick. I've had odd problems that
have been caused by supposedly-insignificant things like spaces or dots
in the HTML.

Nice pics, and they look good against the black background. And the site
is simple and clear - good effort!

This is true, I guess that's where RAR's author got the idea, but the
difference is, ZIP *doesn't* do it, so that's where RAR has an advantage.

It has to do with the premise that (for at least a short section of data)
there are regular patterns in data, so the compressor replaces long
stretches of repeating data with one byte, of course making the file
smaller.  Unfortunately, most binary executables have (seemingly) random
data, so there are no repeating data to compress.  On average, the best
*any* archiver can do for any data is about 50% compression.  That's why no
one has replaced zip as the virtual Wintel standard, because on average, you
can't really do much better.

Hmmmm...  maybe I'll try it out...  I've heard of it, and I'm pretty sure
gnu has a wintel version somewhere.  Speed really isn't an issue to me,
though...  I'll take higher compression over speed any day.

No archiver can compress completely random data, even by 1%.  No one
has proven any bounds on the compression possible for any particular
kind of nonrandom data, partly because most real nonrandom data is very
difficult to characterize mathematically.

It's about twice as slow on compression as gzip, and about thirty times
as slow on decompression.  (gzip decompresses about fifteen times as
fast as it compresses, you see, while bzip2 decompresses just as slowly
as it compresses.)  I think gzip uses the same compression that zip does.

Righto.

BTW, you can get the same effect by creating a .ZIP archive with no
compression, then creating another .zip archive with one file in it --
the first, uncompressed, .zip archive -- and maximum compression.

There's no telling if that's where RAR's author got the idea.

My favorite dos archiver (ARJ) has the -js option that allows you to set all files ending
with the extensions given (e.g. -js.zip.arj) to STORE. Can be very useful. Saves a lot of
time (every tried to pack your Quake dir? :-) and some space.

>btw, bzip2 has usually about 20% better compression than zip, arj,

Yes. Compare these. These are the latest versions of the linux production kernel:

07/13/98 09:09      5,700,498 linux-2.0.35.tar.bz2
07/13/98 09:09      7,014,087 linux-2.0.35.tar.gz

Does there exist a dos (or even windows) version of bzip2? I have it for linux, but
switching to linux every time to compress isn't very practical (I can't connect to the
internet from linux, so I default to windows :-(  ).

The official homepage of bzip2 seems to be http://www.muraroa.demon.co.uk/
and there's a US mirror http://www.digistar.com/bzip2/index.html

The homepage contradicts Kragen's words on speed (but okay, they're not gonna say it's
slow :) :
"bzip2 is a freely available, patent free (see below), high-quality data compressor. It
typically compresses files to within 10% to 15% of the best available techniques, whilst
being around twice as fast at compression and six times faster at decompression".

It doesn't have anything to do with GNU, although open-source (BSD Style license). There
IS a windows version. And a OS/2 version. The supported platforms are:
    - PC, Linux 2.0
    - Sun Sparc, Solaris 2.5
    - Sun Sparc, SunOS 4.1
    - PC, Windows 95/NT
    - DEC Alpha, Digital Unix 4.0
    - IBM RS/6000, AIX 3.2.5
    - SGI, Irix 6.4
    - PC, OS/2 v3.0
    - HP PA/RISC, HPUX 10.20

The latest version of bzip2 available is 0.9.0.

The number of strings of N bits is 2^N.  There are two strings with one
bit, four strings with two bits, eight strings with three bits, etc.
This continues on, even up into the millions of bits.  Also, there are
2^N-1 strings with *less than* N bits.

OK, so if you have a file that's a million bytes long, then it can be
any of 2^8,000,000 different possible files.  And if you have a file
that's a million and one bytes long, it can be any of 2^8,000,008
different possible files.  Simple math reveals that, for every file
that's a million bytes long, there are 2^8,000,008/2^8,000,000 = 2^8
different files that are a million and one bytes long.  In fact, you
can get this in a more obvious way --- given any file that's a million
bytes long, you can append any of the 2^8 = 256 different bytes to get
a file that's a million and one bytes long.

A compression algorithm is a function that maps strings of bits into
strings of bits.  It makes the file shorter if it can map a longer
string of bits into a shorter string of bits.  It makes the file longer
if it maps a shorter string of bits into a longer string of bits.  The
mapping has to be one-to-one, because you want to decompress the
resulting string of bits later to get the original.  If more than one
original compressed into the same string of bits, there'd be no way to
tell which original to reconstruct.

No compression algorithm can compress every million-and-one-byte file
into a file that's a million bytes long or less, because there are only
(2^8,000,001)-1 possible files that are a million bytes long or less,
while there are almost 128 times as many million-and-one-byte files.

Of course, the same argument shows that you can't compress every 500K
file by even one byte, can't compress every 10-byte file by even one byte, etc.

You could do something clever, like come up with 128 different
algorithms, at least one of which would compress the million-and-one
byte file down to a file of a million bytes or less.  Then you could
try all 128 algorithms, and just output the result of the one that gave
you the smallest output.  But wait!  You have to prepend a byte to the
beginning of the file to tell the decompressor *which algorithm* to
decompress with.  (Well, seven bits.)  It turns out that blows away
your compression.

Make sense?

Makes sense to me :-)

However, depending on the storage format of the archive, I guess some bytes are reserved
per file for storage/algo information. Dunno much about pkzip (e.g.), but zips seem to be
using different algorithms (?). I guess so because pkzip is that fancy to show whether
it's compressing, deflating, imploding, or whatever 'algo's'. It seems to me that when an
archiver detects that the file that's added and compressed is actually *larger* then the
original, the archiver can 'store' it instead. I believe ARJ to do this. RAR for instance
'compresses' anyway, but ARJ must be *forced* by a command line option, -jsomething, to do
so (reason ARJ gives to force: encryption). But this is only theory.

ISP. I actually have a free ISP that has to be connected to through a proxy server. Don't
like this for linux - I'm still quite a newbie - hope to change this soon :) . Till now,
I've tried a friend's ISP (GlobalXS). Get thrown off the line in a minute(?). Doesn't seem
completely linux-related; from a windows terminal the same happens. I surfed to the Dutch
Linux Users Group (Nederlandse Linux Gebruikers Groep, www.nllgg.nl) for there are some
dial-in scripts for dutch providers. No one for GlobalXS (which isn't a real small isp,
really). Tried other scripts, puzzled a lot... doesn't seem to work out right.

>I'm sure bzip2 would be pretty easy to compile for DOS.

Sure. I'll try to cross-compile it from linux (djgpp-compiles programs *always* crash

Actually, that is fairly often done to make a site Lynx friendly and Mosaic
friendly. If a browser supports frames it ignores anything after the
frameset info, and if it doesn't, it ignores the frameset info and displays
what follows, which can be a frameless version of the same page. When I
sometimes use Lynx I much prefer seeing that to seeing a blank page, which
is how Lynx and other frameless browsers render an
anally-retentively-correct frameset page. Then I have to hit view source,
and look at the frameset links, and guess which one is the fucking document
and not some toolbar or link list or snazzy logo, and try them by entering
them directly. :P

Is this a new standard for placing something there for frameless browsers

know nobody's going to try viewing a fractal gallery in Lynx, but browsers

I don't think so. Typical binary data compresses about 50%. Some things
(especially already-compressed data!) barely compress at all, or don't
compress. (And storing them in a compressed format will often bloat these!
The decompression data in the header overwhelmes the slim-to-none
compression savings.) But some specific kinds of data compress a great
deal. Even high quality JPG compression can make a fairly uncomplicated
picture shrink by a factor of four, six, eight, even a dozen. Text
frequently compresses 5-10 times under common streaming compression
techniques because of the unused eight bit (redundant, there's 1/8 off the
data size already), the great bias toward only a few bytes (the
alphanumerics, then the space and punctuation, and none of the unprintable
characters at all), and then the frequent occurrence of words ranging from
"the" to fairly substantial ones. Every occurrence of space "the" space
probably becomes a couple byte identifier, saving three bytes for every
such occurrence...
Animations have the same sort of redundancy as regular image data but in
three dimensions, adding to compressibility. MPG can get 100-fold
compression over the raw frame data.

Zip is probably preferred to bzip2 because of the speed. Speed/space
tradeoffs are very common in computing. Many many algorithms can be
mathematically proven to be either slow, space hogging, or some compromise
between the two.

>I'll take higher compression over speed any day.

As with most such tradeoffs, alternate variants that choose differently
usually arise, so that users have their choice of speed versus space.

Why don't they make some up then... Markov chains, chaotic iterations
(veering slightly toward on-topic), and the like all offer means of
creating mathematically exact and anaylzable data with similar
characteristics to real data. (E.g. stock market data.) Also,
typical-looking written text for any language can be computer-generated
with the syntactic and statistical properties of real text (but meaningless
semantics); I've done that myself; and the statistical properties of every
major language are extremely well documented from much analysis of
thousands of written texts, this data being primarily useful for
cryptanalysis and cryptography; it would also be useful for studying the
redundancy and compressibility of text in various languages.

Also, real world data can be fed into a computer for "autocorrelation
analysis". The higher the autocorrelation, the more compressible the data.
The higher the autocorrelation on already-compressed data, the more
horribly inefficient the compression that was used :-)

Note that this is true of most compressions used on computers and all used
on arbitrary data, but false for compression functions used on certain
kinds of data, mainly image, animation, and sound data, where exact
reproduction is not critical. (JPG and MPG are well-known compression
schemes that are for specific kinds of data and are not one-one.)

Certainly. And the proof: the new compression algorithm that picks another
algorithm and chooses the best is also a one-one mapping. You can't climb
out of that box.
You might suppose you could leave out that byte, and use the best
algorithm, and write a *smart* decompresser that somehow can tell which of
the various possible reconstruction is semantically correct and therefore
the original. Your prepended-byte argument wouldn't show it then, but this
could still not achieve perfect compression for the same reason. (After
all, for the hypothetical smart decompresser to work, you could not have
algorithm A turn data A into data C,and algorithm B turn data B into the
same data C. Therefore, it's still one-one without the prepended byte, OR
it isn't one-one and the smart decompresser is impossible.)

>Why can't you connect to the Internet from Linux?

I'm wondering the same thing. A lot of people run frwaking servers off
linux boxes for chrissakes. A sendmail here and an apache httpd there...

That's weird, what djgpp version? 2.02 with gcc 2.8.0 works fine on my
typical w95 install. Do you have w98? Maybe sly old gatesboy stuck an
anti-djgpp directive in it to force developers to buy crummy Microsoft or

nightmares about developers making programs for windows for free and
spreading them for free and never buying (pun intended) into the modern
Western $$$-cult at all.... the horror! Those joyriders ought to stick on
the sinking ship (yeah, right Gates) of Linux where they belong!

Well, Microsoft is managing to make even the steep-learning-curve,
user-unfriendly, wizard-language speaking Linux popular by making Windows
a) less and less popular and b) the only alternative... and other freeware
OSes are in the works.... some written using gnu compilers.... Gates must
feel like this IS a nightmare, everything spiraling down the drain, the

share) not holding, and everything he tries to clutch for himself slipping

I'm more worried when I hear about them 'cause usually they're new and
antivirus software needs to know about them before they can detect them
anyway - so you are never really safe (no need to go into the details, I did
some research and with all the time it would take to keep a proper antivirus
system up to date and functional, it will be quicker and easier for me just
to reformat/reinstall). So really, when it comes to the crunch, *someone*
needs to get infected before they can write the anti (I doubt the creator of
the virus would go to the trouble). Anyway as long as I can reformat,
reinstall etc....its only a major drama, not the end of a computer.

Anyway, because the virus was announced on this list, I thought perhaps
someone on this list (the person who wrote or a related computer) had been
infected, therefore any exe's accessed that they had could be infected etc,
etc..... which means there could be a risk and this IS useful info. There
are *so* many viruses being written daily who can keep up?

Opera has the very nice option to turn frames OFF.

.jpg compression is lossy, and that's a whole different ballgame.  The
image you get out is visually similar to the image you put in, but it's
not the same.

If you have sufficient tolerance for lossiness, you can get any
compression ratio you want, even 1,000,000 to 1.  :)

MPEG is lossy too.

ZIP is probably preferred to bzip2 because (a) bzip2 just compresses
--- it doesn't make archives --- (b) ZIP is widely used already.

Yeah - once you've finished surfin', pull all the JPEGS/GIFS from your
cache into a permanent storage area, such as a folder marked "FractPics"
or something. 

Whenever I find sites of interest, I tend to pull the HTML pages into a
separate folder, and the relevent graphics into a sub-folder, then
manually edit the references in the HTML pages so that I can browse
off-line and still view all and sundry in it's glory. Then I can at
least clear out the cache without losing anything of interest.

For all it's faults, I've found IE to at least name the files in the
cache something relevent to their original names, so linking them is
fairly easy. However, Netscape called them by daft names and I had
difficulty finding which was which (is this normal, or is there
something I haven't set correctly to avoid this?)

Are there points in a Cantor dust other than points that were at some

I do have win98. But the problem was already there when i used win95. Sorry, I can't look
up version number and such right now. But anyway, I'll have to do some more 'research' to
get the exact problem (and solution?).

Fractal compression (amongst others) seems right for data compression, even for no-loss
compression. I dunno about the most recent developments in this area, but I guess the
algo's are far too slow to be useful yet. Or even making the decision which algo to use...

Okay, in that case one can indeed compress 'random' data quite well. But I don't think
this is a valuable option *yet*.

JPEG compression is nothing, nothing like file compression used by archivers and such.
JPEG compression also means losing details, while with the compression we were talking
about, no data is lost (fortunately!).

Again, that's loosely (sp?) compression.

Not even speaking of availability. Not many (wintel) people use it, and even in the unix
world it's not the most used format.

Hmm... makes me remember to set the -9 with gzip -- usually forget this.

Let't just call the language 'German'. 'Foreign' language is a wrong term on the net, not
even considering that the German language is used (or at least known) by a lot of people.

Thank you for all your replies, it was useful and interesting. I have
finally picked up my printed full size picture and it is 50" x  40". Has
anyone sold one of this size? If so, how much for the print itself excluding
framing? (I would add on framing costs as a seperate item at cost) Also,
does anyone
charge a different amount for one that is personally signed? What type of
pen/ink/pencil? What other
forms of unique identification does anyone use? After all, anyone can
produce a print from a file they took from the internet - what we are
creating is art - and the personal touch is required.

For those that aren't aware of them, there are several programs that let
you search the hierarchy of a particular web sites pages/images and
allow you to select what you would like to download and store locally.
Then you can browse those pages offline.

Several are, Black Widow, Teleport, InSite, and maybe others.

Fuzzy hand-waving approach. There are countably many endpoints, ie
aleph-null, because we can enumerate the number of steps of removing the
middle sections, and at each removal a finite number of new endpoints are
created.  So if there are aleph-one points in the dust some of them cannot
be endpoints.

See, the same thought occurred to me.  Then I thought, well, you can
use the same argument for binary numbers: there are countably many
binary strings of aleph-null length, because we can enumerate the
number of steps of appending a new digit, and at each digit-appending,
a finite number of new binary strings are created --- two for each one
that already existed.  But Cantor's diagonalization proof applies here,
so there are more than aleph-null binary strings of infinite length.

You can use Cantor's diagonalization proof in exactly the same way on
the endpoints, it seems to me.

Also, it seems that every point that is not an endpoint will be removed
at some point.

But these are off-the-cuff --- I've probably made an error somewhere up
here.  If not, then I've made an error down below.  I hope someone will
be kind enough to point it out to me.

On the other hand, there's another construction of the Cantor dust:
instead of dividing *all* the line segments at each step, just pick
*one* -- the biggest one, or if there are several of the same size, the
leftmost of the biggest ones --- and cut a chunk out of the middle of
*it*.  If you repeat this for 2^N-1 steps, you get the same thing as if
you'd done the usual Cantor-dust construction for N steps.

So in the limit of N -> infinity, do you still get the same thing?
Because this construction will obviously never produce an uncountable
number of endpoints, right?

I think that is correct...

The points in the Cantor set, if scaled to fill the interval from 0 to 1, are
all the numbers with no 1 in their ternary expression, thanks to the way the set
is constructed.

You can then map all points in the Cantor set to those on the line segment by
replacing each 2 with a binary 1. 

I don't know if that actually helps decide whether all the points are
endpoints.  I suspect all non-repeating strings (irrational numbers) that are in
the Cantor set are not endpoints.  I wouldn't know how to go about proving that
though.

If so, then the number of endpoints is aleph-null because they are at most the
number of rational numbers, while the total number of points is aleph-one.

I use the commercial version of Teleport Pro, v1.28 bld254. It is also available as
shareware. See www.tenmax.com.  The sw-version has one major con: you can only dl a 100
files per project.

There's a project wizard, from which you can do the following:

- Create a browsable copy of a website on my harddrive.
  Says website but any url can be given, including directories.
  Auto-adjusts urls for local use.
- Duplicate a website, including directory structure.
  Just downloads all files. Urls unchanged.
- Search a website for files of a certain type.
- Explore every site linked from a central site.
- Retrieve one or more files at known addresses.
- Search a website for keywords.

This version only works with http (www) servers. I don't know about newer releases.

The Cantor *set* (not dust) consists of the unit interval (the real numbers
between 0 and 1)
         _______________________________
         0                              1
with the middle third removed 
         ___________         ___________
         0       1/3       2/3          1
and then the middle thirds of these two intervals removed 
         ___    ____         ____    ____
         0 1/9 2/9 1/3      2/3 7/9 8/9 1
and then the middle thirds of these four intervals removed and so on. 
If we express the points in trinary (base 3), this process removes
all points with a 1 in their "trecimal" representation.

Of course, 1/3 = 0.1000...(3) but can also be expressed as
           1/3 = 0.0222...(3) and therefore has no 1's.

The trinary representation of left endpoints will be terminating 
trecimals (actually, no decimal or trecimal is terminating, but ends
with an infinite string of 0's)

The trinary representation of right endpoints will be a trecimal
ending in an infinite string of 2's.

The points asked about in the question are those whose trinary 
representation have no digit 1 *and* do not end in an infinite 
string of 0's or 2's.

A good example is 1/4 = .0202020...(3),
a non-endpoint in the Cantor set.

Since the Cantor set consists of all trecimals with digits 0 and 2
exclusively, they look exactly like the binary "becimals" with 2's in
place of 1's. And, in fact, the mapping of the becimals into the 
trecimals (changing the becimal 1's to trecimals 2's) shows there
are as many points in the Cantor set as there are becimals between
0 and 1. These becimals fill the interval entirely and are therefore
aleph-1. Therefore the Cantor set is aleph-1.

Under this mapping, the endpoints of segments in the Cantor set 
correspond to terminating becimals and are a subset of the rationals, 
and therefore aleph-0. 

Therefore "most" points in the Cantor set are not endpoints.

I suggest $500 for the naked print.  I had a 40x40 print made and it cost
about $350, including the transparency.  It's wise to separate framing
from the image, as you did.  For that size of print, framing can easily
cost $500 itself.

I don't usually sign the print, but will if asked.  I would use a Sharpie
of similar permanent marker to sign the print.  Usually, I just sign the
mat in soft pencil or a fine tip marker.

I generally do this when I give away photographs.  A disadvantage
though, is that if the matte is damaged and replaced, the signature is
lost.

Normally, an extra charge is not done.  This is something that should be
graciously given, since they are puchasing your product.  Most artwork
has some form of signature already upon it.

You could acquire a personal customized embosser, like some people use
for their private libraries (similar to a notary seal).

I use a custom electric branding iron that has my signature and company
name (but this is for my wood carvings and turnings).

If you are going to make several prints of a specific image, then you
might consider adding a number with the signature.  To make it more
"valuable" (relative term), just have so many that will ever be printed
and use the old "1 of 200" numbering method.

Subject: (fractint) Par file error
Date: 15 Oct 1998 18:30:40 -0700

	
	Hi, anybody that can help!

	Two problems - (maybe one, that causes the other).
	
	First, I can't remember what key, or keys, I hit that made the screen
suddenly start generating(or revealing) a black and white image.  This
happened to me once before and somebody gave me the answer but it was so
long ago I can't remember what it was.  I have poured over the F1 help
screens, but can't find a solution in there.
	Second - I have been putting a lot of pars in my par files, I have about
200 in each of four, and guessed it was about time to start a new file.  So
I did and I can't seem to get it to work.  When I finally started out of
Fractint, on the black 'Thanks for using Fractint' screen I found the
following message:

"run-time error R6001
 -null pointer assignment- "

	I was very happy that they told me about the error, but I don't know what
it means.

	Can anybody help -with one or the other - or both of these problems?
	I'd be most grateful.

	Thanks				Ray

That makes no sense. I get

Agreed, it is a compression that is tailored to a specific kind of data,
image data. As such it takes advantage of the image data being two
dimensional.

JPEG compression on the highest quality setting doesn't lose information.
JPEG, contrary to popular belief, gives program implementers the option,
and most programs give users the option. (Paint Shop Pro and Ultra Fractal
for starters.)

I'm not as knowledgeable about MPG as JPG, but the name suggests the
formats are cloesly related -- I expect MPG is three-dimensional JPG for
all intents and purposes. I'm pretty sure one can again choose between a
lossless compression and varying degrees of lossier but more compact
compression.

It may be less optimal (accounting for tradeoffs) or it may be obscure and
hard to find/discover that it exists.

>Hmm... makes me remember to set the -9 with gzip -- usually forget this.

Another speed/space tradeoff?
JPG and MPG introduce another tradeoff, the quality/space tradeoff, as a
lossless compression isn't as compressed as a lossy compression setting.

Won't the search engines find this in the body of the html anyways? Or is

How rude!

*sigh* here we go again...
jpg is configurable. There is a quality setting ranging from very lossy and
compact to larger and lossless.
(The latter is the default when saving a jpeg from ultra fractal.)

>If you have sufficient tolerance for lossiness, you can get any
>compression ratio you want, even 1,000,000 to 1.  :)

So, you did know it was configurable, just not that it can be sent to the
extreme of losslessness. (And then the algorithm still takes advantage of
the two-dimensional nature of the data, so it compresses better than saving
a raw bitmap and zipping it.)

MPEG is configurable too.

IE's cache is inefficient though. I've often found it's gone and saved the
exact same large gif in each of four subdirectories in the cache dir! Also,
I keep setting it to 1% of my drive (22 megabytes) and I keep noticing disk
space loss a couple days later and discovering that the disk space fairy
has come and bumped it up to 3% on me -- 66 megs, using up 40 megs.

1. I don't know German, consequently, I didn't know what language it was,
only what language it wasn't.
2. It is foreign from my perspective, see 1.
3. Most users of the Fractint-list are English speaking. Thus it is foreign
from most of our perspectives... although probably not all.

There's a lossless-jpeg option, but it is not widely implemented, and
is not the same as setting the quality setting to 100%.  Even with the
quality at the highest setting, there is loss from roundoff error.

I wasn't referring to JPEG here.  I don't think you can get 1,000,000
to 1 with JPEG --- although I could be wrong!

Fractals don't look too bad with JPEG, especially if they have smooth
color schemes, unless you turn the quality way down.
