I would like to use QuickTime to access some of the file types not
supported by NSBitmapImageRep. The problem is I can't use a file
reference to get the correct graphicsImporter. The imageData is
embedded within a separate file and I have the the imageData within an
NSData object. How time consuming is it to let graphicsImporter guess?
The data image Data can 8 or 16 bit grayscale or 24 bit RGB color JPEG
/ JPEG 2000. If I decided to go directly to decompress and bypass
graphics importer, how hard is it to create an ImageDescriptionHandle
by scratch. Are all the fields in the structure necessary to
decompress? This is probably straight forward but I'm new to QuickTime.
