%  ReadImage() reads an image or image sequence from a file or file handle.
%  The method returns a NULL if there is a memory shortage or if the image
%  cannot be read.  On failure, a NULL image is returned and exception
%  describes the reason for the failure.
%
%  The format of the ReadImage method is:
%
%      Image *ReadImage(const ImageInfo *image_info,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image_info: Read the image defined by the file or filename members of
%      this structure.
%
%    o exception: return any errors or warnings in this structure.
