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.
But NSImage already uses QuickTime for a bunch of stuff what image
doesn't work???
