Use CoreGraphics. The CGxxx APIs let you set a mask on the current graphics context. Essentially you get a CGImage from your NSImage, specify that as a mask for your context, and all white areas will be "clipped away". If you now draw a black rectangle at the yize of your image, you should reproduce the same B/W image you had before, but transparent. -- Uli Kusterer Sole Janitor http://www.the-void-software.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
