Re: CGImageCreate providers invoking

I'm creating a cgimage with CGImageCreate() using the simple provider:

provider = ::CGDataProviderCreateWithData(NULL, data, <size>, NULL);

which I release after calling CGImageCreate()


What I can't seem to find adequate documentation for is:
Is the provider used (once only) during CGImageCreate?

If not I have to keep my data lying around, which is a pain, so I wonder if there's a way to flush it.

Or is the provider something that randomly might get called if the graphics card gets full and I has to re-load the bitmap or something?

The data provider will be used for the life of the image. That's what the last parameter (the one you're setting to NULL) is for. It can be used to release the memory when the image has finished with it.
