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.

66% IdentifyImageCommand() describes the format and characteristics of one or
67% more image files. It will also report if an image is incomplete or corrupt.
68% The information displayed includes the scene number, the file name, the
69% width and height of the image, whether the image is colormapped or not,
70% the number of colors in the image, the number of bytes in the image, the
71% format of the image (JPEG, PNM, etc.), and finally the number of seconds
72% it took to read and process the image.
73%
74% The format of the IdentifyImageCommand method is:
75%
76% MagickBooleanType IdentifyImageCommand(ImageInfo *image_info,int argc,
77% char **argv,char **metadata,ExceptionInfo *exception)
78%
79% A description of each parameter follows:
80%
81% o image_info: the image info.
82%
83% o argc: the number of elements in the argument vector.
84%
85% o argv: A text array containing the command line arguments.
86%
87% o metadata: any metadata is returned here.
88%
89% o exception: return any errors or warnings in this structure.
