Sorry, forgot to say that I have looked at the IKPictureTaker and it
isn't really what I'm looking for. I don't want the user to be able
to choose a picture or anything like that, I just want to take a
picture when the user clicks a button for example or when I call a
method in my code. Is this possible?
I don't need to support pre-Leopard.
A cursory scan of the docs suggests to me that a good place to start
looking would be QTCaptureDecompressedVideoOutput. This sends a
CVBufferRef to the delegate during capture, and there are methods
associated with that class to get basic information such as base
address, row bytes, height and so on, which would allow you to wrap
that buffer in a NSBitMapImageRep and from there to an NSImage and so
on....
So, that's probably what I'd be initially pursuing if it were me, but
take that with a pinch of salt as I might be way off.
