That's right, I was not doing it correctly, this is now working.
Also I noticed I can call CGImageCreateWithImageInRect to create a
new CGImage which is a smaller area of the original image and then
call CGImageGetDataProvider and CGDataProviderCopyData to get the
pixel data.
Seem easier and faster too. However CGDataProviderCopyData is 10.5
minimum.
Unfortunately due to a bug that doesn't always work correctly. If you
file a bug, reference bug 5889934.
