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.
