I have to upscale JPEG images from 72DPI to, say 250DPI (user-selectable). I figured Core Image would be the way to go, but...

I don't know a Core Image filter for that, but it seems like a natural thing to expect. You might want to ask on the Quartz mailing list.

It's definitely possible to do bicubic scaling with QuickTime, though I haven't tried to do that since the days of GWorlds. -- James W. Walker, Innoventive Software LLC <http://www.frameforge3d.com/> _______________________________________________
