I'll be out of town until Sunday. The list can continue as normal
(though "normal" lately is quiet <g!>) though I won't be able to
handle any special list administration requests until I get back.

Subject: (fractdev) Integer math
Date: 17 Oct 1997 21:17:23 -0600

We had a discussion on CompuServe about integer math, and everyone
(even Bert Tyler, the original author) voted yes. It will be done.
This will buy us a whole lot of space in the DOS version. I'll find
out how much as soon as possible.

While extending the life of the DOS version, this will also move us a
step closer to portability.

I have also raised the question of removing all fractal types that
can be implemented in parser formulas. This would further simplify.

Right now I am thinking of a truly major new release of fractint. We
never have schedules around here, but just to put ideas in peoples
head, I'm thinking of a June release target.

The new fractint version 20.0 will have no integer math, but will
have SOI, PNG, and truecolor support. It would have a new method of
storing parameters in images (probably PNG images - we might drop GIF
support altogether, or we might leave in GIF decoding but not
encoding.)

I don't anticipate a new GUI in the June time frame, but Fractint
20.0 would be written with an increase of portability and a better
architectural isolation of the underlying engine in mind.

Any comments?

Tim

The Gods have spoken!

See my response in another reply.

>>The new fractint version 20.0 will have no integer math, but will have
SOI, PNG, and truecolor support.<<

You might also want to consider anti-aliasing options.

>> It would have a new method of storing parameters in images (probably P=

I would prefer to have GIF decoding for at least 1 or 2 more years after
PNG is implemented.

Is this along the lines of storing the PAR as a plaintext comment in
the image?

You should be able to get this with the tiling options, right?

Rich,

I said to Tim:

You replied:

Please explain.  What tiling options are you referring to?

When you use the 'B' command to make a PAR from the current set of
configurations, it asks you if you want to tile the screen with a grid
of NxM images.  If you tile your image with a 3x3 grid of images,
stitch the 9 images together in a mosaic and then downfilter, you've
just anti-aliased your fractal.

Rich,

But Fractint doesn't downfilter.  This discussion was what should be adde=
d
directly to Fractint itself.  Once any post-processing is done, the image=

can't be zoomed, pars can't be made to construct the same image, etc. =

Since Zplot and FractalXtreme both support anti-aliasing, I was just
suggesting that Fractint also support it.

Yes, though not as a comment. I have reserved a special PNG chunk for
this purpose.

We never thought of portability when we wrote binary numbers to a
file. Ken Shirriff went to a lot of trouble to make Xfract read our
fractal data! We don't need to repeat that mistake when we go to PNG.
