Introduction to Image Kit Programming Guide
The Image Kit is an Objective-C framework, introduced in OS X v10.5, for browsing, viewing, editing, and processing images in an efficient manner. It also supports browsing Core Image filters, previewing the effects, and providing controls for individual filters. This document describes Image Kit user interface elements and shows, through code examples, how to use Image Kit classes.
Anyone developing a digital media application that supports images will want to read this document to find out how to use the Image Kit to provide the best user experience possible. You don’t need to be a seasoned Cocoa programmer to use the Image Kit or to read this guide, although prior experience with Objective-C is helpful and will make it easier to understand the code examples.
The examples in this document use Xcode version 3.0 and Interface Builder version 3.0.
At a Glance
