You should have a look at a JPEG decoder like Sun's
JIMI or Sun's JAI (Java Advanced Imaging API).
You might find some usefull methods regarding the
color model used by a JPEG image file.
Wandering around JAI's JPEGImageDecoder, it
extends ImageDecoderImpl.
There's a method called decodeAsRenderedImage(),
which returns a RenderedImage
Then you can call
getColorModel().getColorSpace().getName() or getType() on this
RenderedImage
and you should have an int representing the color
model (CMYK, RGB, etc...)
I havent tested it myself and I'm not an expert in
JAI, but I guess it should work.
Hope it helps !
