Could it be the CGImage references a compressed image format rather
than a bitmap?

What is killing me here is that the CGImage has dimensions 417x234

am obtaining should be 390,312 bytes (234 x 1668). But the
CFDataRef is only 6,672 bytes which is nowhere close to what I think
I should be getting. So I must be doing something wrong in trying
to get the bitmap data, but I'm not sure what else to do and I even
found some Apple docs with an example doing the exact same thing
that I am doing. Can anybody provide some insight on this? Thanks
everybody.
