Wait, you're trying to color-match against a specimen by _reading color values from the screen?_ Does this not strike you as unnecessarily circuitous? Or fragile? Or prone to unwanted interference from monitor color calibration? Why not use ImageCapture to actually get the images straight from the input device? Or if the user already has an image (preferably with an embedded color profile), let them import the image file directly. Then you can present your color sampling interface without any silly screen-reading trickery. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
