A question: What is the recommended way of using Quartz to
display bitmaps?
And Am I right in thinking (from what I've read) that Quartz supports
1. Transparency
2. Scaling/Rotation
Yes to both of these.
3. Animation (via Animated GIF's)
Quartz does not have any built-in support for loading images
from files. This is usually handled either through Quicktime or
Cocoa's NSImage class. As for animated GIFs specifically, you
might want to take a look at Omnigroup's free frameworks,
specifically OIF (Omni Image Framework).
4. Movement/Loading of Bitmaps
Automatically?
I'm not quite sure what you mean by this question.
If so, how does one go about the process of loading/displaying a bitmap
using Quartz. The only examples I could find were about getting
a Quartz
Bitmap Context, which I have no idea what that means either.
If you're using Cocoa, you usually don't have to call Quartz
directly - you can just use the NSImage class to load and
display the image in a view.
