Cocoa: Quartz, Core Graphics, Context vs View. Oh My!

Question

Heads starting to hurt. I think I dropped into this too fast... Perhaps someone could help me visualize how these (excluding OpenGL ES) high level drawing libraries fit together - or point me to some high level docs. For example I see "context" and "view" used interchangeably in some cases but a view has one (only one?) context while a context doesn't have a view?!?

Nothing too elaborate just need help visualizing their differences and their boundaries (when to use one as opposed to the other).

Answer 1

Here's a document with a graphic showing the relationship between these technologies, and an explination of contexts:

It's under the "Core Image Programming Guide" overview if the link breaks again.
