Jared, TIFF, is a standard that is recognized for both Macs and IBM's. If the images are in color, I think GIF, might be the way to go. TIFF is a standard accepted mostly by desktop publishing companies. It was designed by Aldus, and several other companies to be a standard for desktop pubilishing. The developers made the source code for reading, writing, and compressing images public domain, so any vendor could easily make his application read and write TIFF files. It definitely works on IBM's and Mac's. I know that it works well for B&W and grayscale images, but I've never used it with color, so I'm not sure. -Todd

If the >images are in color, I think GIF, might be the way to go. TIFF is a Unfortunately TIFF isn't so much a standard format as a standard wrapper. I have maybe a dozen Mac programs that read TIFF, and some of them can read each other's files and some cannot. I have two or three Unix programs that can read TIFF too, and some of them are compatible and some aren't. There's no real telling. There are some TIFF formats which are more common than others, but in general it's a real mess. I'd go for GIF, except that it's limited to 8bit images. -- Alfalfa Software, Inc. | Poste: The EMail for Unix nazgul@alfalfa.com | Send Anything...

TIFF (5.0 and above) is also for color images as well. It's fairly easy to
write TIFF, but more difficult to read TIFF in the most robust, general way,
because of the richness of what's available.
For example: The picture may be broken up into several strips, the ordering of
the strips in the file can be arbitrary, these strips do not need to be
contiguous in the file (there can be superfluous bytes in the file, presumably
to "word align" the strips), your color image can be pixel, line, or frame
interleaved, etc., etc., etc. . . .
If you just want to write files, or read files that you've written yourself,
you might want to consider using a subset of TIFF.
