David, We (Reference Technology) typically use CCITT Group IV compression
for parts-manual type applications with line drawings. Compression is much
better than PCX: usually averages around 20:1 or better. If you have any
significant amount of half-tone material, however, things get worse in a
hurry! Group IV is a lot more difficult than PCX to decompress: you'd
probably be better off buying that technology (from us, for instance ….)
than re-inventing it. Tony Lavender
