I have examined the GIF format (version 87a, is there a better one out?) and found that it is too limited to handle the images I will be producing. Of course I could always cut the quality and fit them in, but I'd like to make the full images available as well. In particular, the GIF limit of 256 different values each pixel may have is the most limiting factor. Also, there doesn't seem to be a way to code an image without a color map. I'd like to look into the TIFF format, but I cannot find documentation. I go onto a NeXT machine and searched every file I could and found no documentation on the TIFF format. What other formats are there? Should I create YAIFS (Yet Another Image Format Standard)? I'm sure there are already plenty, but I can't find documentation on any that seem like they can work. phil howard
