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

       For some formats, additional  format-specific  information
       about  the  file  will  be  written if the -debug coder or
       -debug all option is used.


OPTIONS

       Options are processed in command line  order.  Any  option
