Thread: GIF, LZW Patent Issues
face BY : Mike Hardwick email (remove spam text)

Exactimo. The embedded system I'm developing has to *display* images, which
means that it must decode the files. If they are GIFs, then my system has
to use the LZW algorithm. The best deal we could negotiate with Unisys
involved a large advance payment. We decided to make a custom file format,
but I would rather use a standard. Whatever we use, it has to support
transparency because the system uses images for video overlay. MIFF and PNG
were the best candidates I found, but their code distributions are too
massive to be useful. Any ideas?
