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  com-
       ment:


           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

OPTIONS
       Options  are processed in command line order. Any option you specify on
       the command line remains in effect for the set  of  images  immediately
       following,  until the set is terminated by the appearance of any option
       or -noop.

       For a more detailed description of each option, see ImageMagick(1).

       -debug enable debug printout

       -density <width>x<height>
              vertical and horizontal resolution in pixels of the image

       -depth <value>
              depth of the image

       -ping  efficiently determine image characteristics

       -sampling_factor <horizontal_factor>x<vertical_factor>
              sampling  factors  used  by  JPEG  or  MPEG-2  encoder  and  YUV
              decoder/encoder.

       -size <width>x<height>{+offset}
              width and height of the image

       -verbose
