Primarily because people abuse the resolution field, and as such it cannot be trusted for this particular function. In a perfect world, we would only ever see 72 (1x) or 144 (2x) in the resolution field, but instead the value tends to be practically random. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
