% ReadDNGImage() reads an binary file in the Digital Negative format 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 ReadDNGImage method is:
%
% Image *ReadDNGImage(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.
