Hey, if anyone has any information on 3200-color "standard" formats, let me
know.  I had the net address of the guy who wrote the View 3200 program, but I
lost it!  &^%!@!
 
Having given up my editor project (because ROSE and MicroEMacs seem to do
almost everything my editor was going to do...)  I am hard at work on a IIgs
UnGiffer.  The Apple // already has an excelent ungiffer for hi-res and
double-hires (what, no lo-res?), and SHRConvert has a few limitations.  SO I
am looking at the following specs:
  * View any size GIF (at least as big as you have memory for).  I have a few
    1024 x 768 GIFs to stretch-test this out!
  * 5 pallette modes: standard 16-color best-fit, 16-shade grey-scale, default
       pallette, and two special modes:  16 best-fits 16-color pallettes (for
       use with something that can handle it like CheapPaint, which I'll have 
       to got, or Color N Canvas), and 3200-color mode, where we have a
       different pallette for every line.
  * Standard compression (squeeze 640*400 to 320*200, etc.)

I also want to be able to save the pictures, of course.  The first five types
(oops, 4 types) are standard.  The 3200 color picture files are NOT standard. 
I am most interested in the 3201 format, which includes compression.  I may
have to implement an extension for multi-screen documents.  So I need the file
formats, or I'm going to have to disassemble a lot of code.
