Hi !
I'd like to implement libjpeg inside a cocoa app in order to
decompress quickly (and progressively which I think NSImage doesn't do),
then draw at will inside
the draw method of an NSView.
I'd like to know what is the best "offscreen" format in which to render
it after decompression so that integration with NSImage will be easier,
or rather,
would it be better if I decompressed it in an offscreen then used
copybits (or whatever is the equivalent now)?
libjpeg outputs in PBMPLUS PPM/PGM, GIF, BMP, and Targa (that's what the
doc says, but I haven't started snooping yet).
Or maybe someone has already done that type of thing and could give me
some pointers/classes ??
thanks
