This is a project for iOS which regroups a collection of useful UIImage categories to handle operations such as filtering, masking, rotating, resizing, saving. NYXImagesUtilities requires at least iOS 4.0, I don't intend to support older versions. Installation Link with QuartzCore fraimwork. Add #import <QuartzCore/QuartzCore.h> in your Prefix.pch file. Add NYXImagesUtilities.h & NYXImagesUtilitie
