% The identify program describes the format and characteristics of one or more
% image files. It also reports if an image is incomplete or corrupt. The
% information returned includes the image number, the file name, the width and
% height of the image, whether the image is colormapped or not, the number of
% colors in the image, the number of bytes in the image, the format of the
% image (JPEG, PNM, etc.), and finally the number of seconds it took to read
% and process the image. Many more attributes are available with the verbose
% option.

% IdentifyImageCommand() describes the format and characteristics of one or
% more image files. It will also report if an image is incomplete or corrupt.
% The information displayed includes the scene number, the file name, the
% width and height of the image, whether the image is colormapped or not,
% the number of colors in the image, the number of bytes in the image, the
% format of the image (JPEG, PNM, etc.), and finally the number of seconds
% it took to read and process the image.
%
% The format of the IdentifyImageCommand method is:
%
% MagickBooleanType IdentifyImageCommand(ImageInfo *image_info,int argc,
% char **argv,char **metadata,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image_info: the image info.
%
% o argc: the number of elements in the argument vector.
%
% o argv: A text array containing the command line arguments.
%
% o metadata: any metadata is returned here.
%
% o exception: return any errors or warnings in this structure.
