Hi Simon-
I tried to answer your first request, but couldn't find horizontal
flips specifically in the core image docs. Rotation is in there.
Here was what I was going to suggest:
Example of image processing in Core Image:
file:///Developer/ADC Reference Library/documentation/
GraphicsImaging/Conceptual/CoreImaging/ci_tasks/chapter_3_section_4.html
List of Apple provided CIFilters:
file:///Developer/ADC Reference Library/documentation/
GraphicsImaging/Reference/CoreImageFilterReference/Reference/
reference.html
On that list, look at CIAffineTransform. In fact, Take a peek at
NSAffineTransform... perhaps you could supply some strange input
values (negative ones) and get the desired result.
Sorry I don't have an actual *answer*, hopefully the links will help!

Have you looked into CoreImage?
That you for the prompt response Ricky. I *have* looked at CI, but
again, I
must not be looking at the right things. I see things like filters,
vectors, etc., but I can't seem to track down anything that
performs "basic"
tasks like rotation & flipping.
Any specific pointers to the docs would be greatly appreciated!
