% Method ReadRGBImage reads an image of raw red, green, and blue 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 ReadRGBImage method is:
%
% Image *ReadRGBImage(const ImageInfo *image_info,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: Method ReadRGBImage 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.
