The idea is that you start using the double sized image starting just above scale 1.0. That way, you are scaling the image *down*, and this always looks good. When the scale reaches above 2.0, you switch to the quadruple-sized image (if you have one). As I said, look at the Photoscroller example which shows this happening automatically (because CATiledLayer asks for a redraw automatically at those moments). Don't forget to test on a double-resolution device (or in the Simulator) because this can change some of the arithmetic. You may have to take into account both the scale of the zoom and the scale of the screen. It depends on the details of your implementation. m. -- matt neuburg, phd = [email protected], http://www.tidbits.com/matt/ pantes anthropoi tou eidenai oregontai phusei Among the 2007 MacTech Top 25, http://tinyurl.com/2rh4pf AppleScript: the Definitive Guide, 2nd edition http://www.tidbits.com/matt/default.html#applescriptthings Take Control of Exploring & Customizing Snow Leopard http://tinyurl.com/kufyy8 RubyFrontier! http://www.apeth.com/RubyFrontierDocs/default.html TidBITS, Mac news and reviews since 1990, http://www.tidbits.com _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
