Also, this is incorrect. This assumes two things - that colour components have 8 bits and that all bits set represent full brightness of the component. Both of these things depend on the colour space. Typically, colour components are expressed as a float value between 0 and 1.0 relative to the colourspace, and are mapped to the actual number of bits per component (modulo colour calibration) in a bitmap internally. The colour model of Windows 3 (and Colour QuickDraw for that matter) are long behind us. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
