Defining UIImage Color Space

Question

I am wondering if there is an easy way to get the color space of an image (i.e. an image loaded into UIImage)? For example, I have a TIFF image, and I would like to determine if it uses the RGB color space or not. Is there an easy way to do this without manipulating pixel data? I know that there are some CGColorSpace functions, but none of them seem to do this, just create color spaces and manipulate them (and much more complex functions).

Thanks in advance.

You need to get the color space through CGImage. You can do this with the following line of functions / properties:

@property(nonatomic, readonly) CGImageRef CGImage

CGColorSpaceRef CGImageGetColorSpace (
   CGImageRef image
);

, , :

CGColorSpaceRef colorspace = CGImageGetColorSpace([myUIImage CGImage]);

, , get/create/copy CG.
