I haven't tried this, but I think you have to provide your own DeviceN color profile to CGColorSpaceCreateICCBased(). Quartz will fall back to the alternate colorspace that you provide for drawing to the screen but I think the ICC data and colors should still make it into PDFs. Again, I haven't tried this myself, this is simply my recollection from having investigated this pathway in the past. -- David Duncan _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
