This application shows how to programatically grab screenshots on a Mac using several technologies:

• QuickDraw
• OpenGL
• Quartz
• Some weird window hack, that doesn’t work for me :(
• Using an NSTask wrapping the /usr/sbin/screencapture utility

The application is structured in such a way that new methods to make screenshots could be added in the future seamlessly.

As always, I’m not responsible for what you do with this code, or what happens when you use it! Do it on your own risk!
