13 The identify program is a member of the ImageMagick(1) suite of tools.
14 It describes the format and characteristics of one or more image files.
15 It also reports if an image is incomplete or corrupt. The information
16 returned includes the image number, the file name, the width and height
17 of the image, whether the image is colormapped or not, the number of
18 colors in the image, the number of bytes in the image, the format of
19 the image (JPEG, PNM, etc.), and finally the number of seconds it took
20 to read and process the image. Many more attributes are available with
21 the verbose option.

64 By default, the image format of `file' is determined by its magic num‐
66 ber. To specify a particular image format, precede the filename with
67 an image format name and a colon (i.e. ps:image) or specify the image
68 type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for
69 standard input or output.
