%  ReadDNGImage() reads an binary file in the Digital Negative format and

%  and returns a pointer to the new image.

%  The format of the ReadDNGImage method is:

%

%      Image *ReadDNGImage(const ImageInfo *image_info,

%

%  A description of each parameter follows:

%

%    o image_info: the image info.
