Try drawing the text offset by 0.5 points. Fuzzy drawing like that usually means that, at some point, you're drawing "between pixels". Since the mathematical coordinate system actually passes each pixel at the upper left, to get a line that lies on a pixel, you generally have to draw offset by 0.5 pt to hit a pixel straight on. OTOH, I think drawing an NSImage usually needs to be done at a 0,0 coordinate (because the upper left of an NSImage is also at a full logical coordinate and everything has already been drawn offset twice). If it's not your drawing code, you may have a view whose coordinates are not on a x.0 boundary, which can cause all sorts of weird things like that because it indirectly causes drawing like that. You can see that in the NIB by looking at the numbers in the inspector. Keep in mind that the coordinates of a superview could be wrong in this case as well. -- Uli Kusterer "The Witnesses of TeachText are everywhere..." http://www.masters-of-the-void.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
