Core Image Reference Collection

Introduction

The Core Image class hierarchy is rooted in the Foundation framework class NSObject. You can use Core Image classes to:

• Process images using existing image filters

• Create custom filters either for your own use or to package as image units

• Chain together filters and then archive them for later use

Core Image is designed to:

• Leverage programmable graphics hardware when possible

• Be easy to use and to extend. You can use the Core Image API even if you don’t know how to use Open GL, access pixel buffers (pbuffers), or perform other low-level graphics-processing tasks

• Provide access to a rich set of plug-in filters and yet allow you to create custom filters that you can publish for use by others
