% ReadMPRImage() reads a Magick Persistent Registry image as a blob from
% memory. It allocates the memory necessary for the new Image structure and
% returns a pointer to the new image.
%
% The format of the ReadMPRImage method is:
%
% Image *ReadMPRImage(const ImageInfo *image_info,
% ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image_info: the image info.
%
% o exception: return any errors or warnings in this structure.
