I have NVDI 2.5 ...
Of course things could be much easier (and programs much smaller)
if everybody would have NVDI 5.0 or fVDI 1.0.

Thanks for the sources you mentioned later.  I will check them
out.  For non-Atari-specific stuff (like dithering, colormapping)
the sources to the libjpeg are also valuable.  And the utils
section of xscreensaver has some interesting things too.

Get a shareware image viewer and ask the author for some bits
of code... ;-)

I will look for MGIF.  BTW, before you GPL it, have you checked out
that you won't get into trouble with Unisys?

Source for libmagick?  Sorry, but I never heard of it.

Hm, they can probably rely on a fixed-size (16 or 256 colors) palette.

And where is AtariQuake?

I will first try to get things working in plain C and then
optimize the code with the assembler pieces you mentioned later.
I still think that a relatively high-level library for these
things makes sense.  You don't want to read hundreds of pages
just to display a tiny 256-color icon.

Ciao and thanks.

Guido
