Hi all,

I need to find out what color space an images uses. I have not found a good solution for it.

The only thing one could do is something like this;

	CGColorSpaceRef inCS = CGImageGetColorSpace(inImage);
	int num = CGColorSpaceGetNumberOfComponents(inCS);

	if( num == 4 && bitmapInfo & kCGImageAlphaNone) {
		--> CMYK
	} else {
		--> RGB
	}

This is somewhat lame and probably not accurate in all cases. Are there any better options?

Regards

Dominik
