I would expect that while the GIF file is smaller, this is because it first reduced the figure to a 256-color palette. PNG can be truecolor, in contrast. My GhostScript does not support GIF anyway, probably because of the patent issues. This leaves PNM, and the above underlines that native PNG support would not be the worst idea. A typical computer will be quite faster reading 2640 byte from disk and uncompressing to 280kB than it could be just reading in 280kB of uncompressed data. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum Email: [EMAIL PROTECTED]
