Subject: GIF decompression ? ? ?
I'm posting the following note for a friend of mine who does not normally
read Info-Apple. Could you please send all replies to him. Thanx.
====================================================================
I am looking for Pascal source code to do LZW decompression (the form
of compression used in GIF pictures). If anyone can send me source code
for this, or has any ideas on how to do it please let me know. I know
the code is in Jason Harpers SHRConvert program, if I could get source
code from this it would be ideal. I am trying to convert GIF files to
a raster format for a CALCOMP(tm) color plotter at my university, and
I am also trying to write a program that will patch up some corrupt
GIF files. I have most of the code to read GIF files already written,
but there is a bug in my decompression routine that I can't figure out.
Thanks in advance,
Steven Pelletier
