High Quality Scaling of UIImage

Question

I need to scale the resolution of an image coming from a view layer in an iPhone application. The obvious way is to specify a scale factor in UIGraphicsBeginImageContextWit

Answer 1

I suppose you could use something like imagemagick. Apparently it's been successfully ported to iPhone: http://www.imagemagick.org/discourse-server/viewtopic.php?t=14089

I've always been satisfied with the quality of images scaled by this library, so I think you'll be satisfied with the result.
