NAME
       identify - describe an image or image sequence.

SYNOPSIS
       identify file [ file ... ]

DESCRIPTION
       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: images/aquarium.miff
	   class: PseudoClass
	   colors: 256
	   signature: eb5dca81dd93ae7e6ffae99a527eb5dca8...
	   matte: False
	   geometry: 640x480
	      depth: 8
	   bytes: 308135
	   format: MIFF
	   comments:
	   Imported from MTV raster image: aquarium.mtv
