I didn't find any documentation about CGDataProviderCopyData() except this comment in the header:

What is the expected output format of the data it returns ?

The output image data is the same format as the associated CGImageRef. You can use the CGImageGet*() functions to determine the exact format of the data returned. -- David Duncan Apple DTS Animation and Printing email@hidden
