%  IdentifyImage() identifies an image by printing its attributes to the file.
%  Attributes include the image width, height, size, and others.
%
%  The format of the IdentifyImage method is:
%
%      MagickBooleanType IdentifyImage(Image *image,FILE *file,
%        const MagickBooleanType verbose,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image: the image.
%
%    o file: the file, typically stdout.
%
%    o verbose: A value other than zero prints more detailed information
%      about the image.
%
%    o exception: return any errors or warnings in this structure.
