36% The identify program describes the format and characteristics of one or more
37% image files. It also reports if an image is incomplete or corrupt. The
38% information returned includes the image number, the file name, the width and
39% height of the image, whether the image is colormapped or not, the number of
40% colors in the image, the number of bytes in the image, the format of the
41% image (JPEG, PNM, etc.), and finally the number of seconds it took to read
42% and process the image. Many more attributes are available with the verbose
43% option.

65% IdentifyImageCommand() describes the format and characteristics of one or
66% more image files. It will also report if an image is incomplete or corrupt.
67% The information displayed includes the scene number, the file name, the
68% width and height of the image, whether the image is colormapped or not,
69% the number of colors in the image, the number of bytes in the image, the
70% format of the image (JPEG, PNM, etc.), and finally the number of seconds
71% it took to read and process the image.

73% The format of the IdentifyImageCommand method is:

75% MagickBooleanType IdentifyImageCommand(ImageInfo *image_info,int argc,
76% char **argv,char **metadata,ExceptionInfo *exception)
77%
78% A description of each parameter follows:
79%
80% o image_info: the image info.
81%
82% o argc: the number of elements in the argument vector.
83%
84% o argv: A text array containing the command line arguments.
85%
86% o metadata: any metadata is returned here.

88% o exception: return any errors or warnings in this structure.
