Resolution independence. Your physical screen may have 96 pixels per inch, but the system exposes it as 72 points per inch. In the case of printing, it actually gets this right and maps these virtual points to physical, real-world 1/72 of an inch. In the case of onscreen graphics, the system currently does not do the points -> pixels mapping such that 1 point = 1/72 inch. You can turn that on with Quartz Debug, though, and then everything behaves as if you were printing. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
