NAME
       identify	 -  describes  the  format  and characteristics of one or more
       image files.

SYNOPSIS
       identify [options] input-file

OVERVIEW
       The identify program is a member of the ImageMagick(1) suite of	tools.
       It describes the format and characteristics of one or more image files.
       It also reports if an image is incomplete or corrupt.  The  information
       returned includes the image 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 (by default off use -define unique=true option),
       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. Many more attributes are available with the verbose option.

       By  default, the image format of `file' is determined by its magic num‐
       ber.  To specify a particular image format, precede the	filename  with
       an  image  format name and a colon (i.e. ps:image) or specify the image
       type as the filename suffix (i.e. image.ps).  Specify 'file' as '-' for
       standard input or output.
