Gif Compressor

[Biterider]

Hi
I need some help with a GIF compressor (LZW algo). Has somebody written it in asm?

Regards,

Near the bottom is a GIF library ported for MASM32 :)

Hi Jojodi
Thanks for the link, but the sources are for a decompressor only...  :(

The gif compression method is patented. Which means if you do implement it, you would have to pay :P
Strangely, the patent was granted twice (maybe for slightly different versions?) - one of those has now finished, and the other is due to finish soon (in a year or two, I think.)

Hi Gabor
Thanks for the link, I will see what I can use  :thumbu

Hi Tedd
As far as I know, both patents expired last year, but correct me if I'm wrong...
