UIImageEffects demonstrates how to create and apply blur and tint effects to an image using the vImage, Quartz, and UIKit frameworks. The vImage framework is suited for high-performance image processing. Using vImage, your app gets all the benefits of vector processing without the need for you to write vectorized code.
