%  Method ReadCMYKImage reads an image of raw cyan, magenta, yellow, and black
%  samples and returns it.  It allocates the memory necessary for the new
%  Image structure and returns a pointer to the new image.
%
%  The format of the ReadCMYKImage method is:
%
%      Image *ReadCMYKImage(const ImageInfo *image_info,
%        ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image:  Method ReadCMYKImage returns a pointer to the image after
%      reading.  A null image is returned if there is a memory shortage or
%      if the image cannot be read.
%
%    o image_info: Specifies a pointer to a ImageInfo structure.
%
%    o exception: return any errors or warnings in this structure.
