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:

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.
