Where to go from here

We've provided a ready-to-compile Cocoa sample project in Objective-C. You'll find the sample in the Sample folder. For your convenience, we also provide a pre-compiled, ready-to-run i386 binary of the sample, you find it in the Build/Debug folder of the sample.

The sample is a simple Cocoa view-based application that exposes some of the Dylib's properties to the user; the end result looks like this:

The relevant parts of the sample source code have been extensively commented to give you a starting point. The sample also contains some utility functions that deal with CGImageRef / NSImage conversion and PNG export.
