If you you're thinking about getting the path data encoded in the PDF:
no dice. Although Apple obviously has this data in Quartz someplace,
there is no API for getting at it. All you can do with a PDF is render
it or embed in another PDF.
so I can draw a beautiful pulsating curvy outline around this image.
Actually, I want to do a lot of different things with the image data --
but that's my problem. Being a relative newcomer to Cocoa, I can't
figure out any obvious way to work with NSImage data except in a very
high level way (resizing, rotating etc).
If you want to get the bitmap data, you can get that into an
NSBitmapImageRep using the -initWithFocusedViewRect: method (with the
current focus either on a view as the name suggest, or on an NSImage for
off-screen use).
After checking the reference documentation, I'm not even really sure
where to start looking. After the 10.1 release, I was disappointed to
still find a large amount of "Description forthcoming"'s still present
in the docs.
Hmm, NSImage and NSBitmapImageRep are fairly well documented.
