Actually the best format for image size and accuracy (especially for 2
colors, is TIFF (packbits).  a GIF works the same way - it just compresses
the like colors for each line. If you have Win95 the built in Xerox (now
Kodak) imaging controls deal with TIFF quite well. JPEG tries to compress
areas, and does a lousy job with straight lines and text, and because it is
a lossy compression will actually mess up the image if the compression is to
high.

so IMHO use GIFF if you want everybody to be able to deal with it (pcx is a
very good second choice for compatibility), But for the best storage of a
LOT of schematics and engineering drawings in general use TIFF (packbits).
