identify - describe an image or image sequence.
identify file [ file ... ]
Identify describes the format and characteristics of one or more image files. It will also report if an image is incomplete or corrupt. The information displayed includes the scene number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image. An example line output from identify follows:
images/aquarium.miff
640x480 PseudoClass 256c
308135b MIFF 1s
If -verbose is set, expect additional output including any image comment:
Image:
