Since a lot of time the color profile stuff is a display-only operation, doing the lcms transform in hardware on the GPU would be basically "free". > This was a few years ago, maybe more modern cards have enough > bandwidth that you would see a speedup vs. the CPU. Almost certainly, as long as the transform can be baked into a 3D LUT. -- Paul Miller | [EMAIL PROTECTED] | www.fxtech.com | Got Tivo? ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
