This sounds a bit odd, until you realise that images can have any resolution (including none, for PDFs), so this size is the size the image scales to, in points, when drawn in a Quartz context. Instead you need to work with the bitmap image representation that the image holds (or create one if it doesn't have one). In fact this latter approach might be the most general and safest anyway, so you can work with PDF images, etc. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
