First of all, we're talking about 24-bit color image manipulation and processing here, so PixMate is completely out of the picture. On the PC, for example, there's a piece of software which sells for $199 which merely reads in a Targa file, converts it to 8-bit color and writes it out in PCX format. This is the kind of bang/buck comparison which was being made. FBM, which is free, is nice. It's slow. It's also not for everyone (i.e. It has no 'real' user interface.). As to color separation, what was being discussed was the complicated matter of converting 24-bit color RGB data into professional-quality cyan, magenta, yellow and black four-color separations. This is not something which can be done properly in an evening of hacking, believe me (or the dozens of people in comp.graphics who have spent more time musing over the problem than I have). If FBM suits your needs, great! There are many people whose needs it doesn't suit, and for those people there are now good, commercial solutions available. - Aaron -- Aaron Avery, ASDG Inc.
