NAME
       identify	 - describes the format	and characteristics of one or more im-
       age 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.

       For more	information about the identify command,	point your browser  to
       file:///usr/local/share/doc/ImageMagick-7/www/identify.html	    or

	 -virtual-pixel	method
			      virtual pixel access method

       Image Operators:
	 -channel mask	      set the image channel mask
	 -grayscale method    convert image to grayscale
	 -negate	      replace each pixel with its complementary	color

       Miscellaneous Options:
	 -debug	events	      display copious debugging	information
	 -help		      print program options
	 -list type	      print a list of supported	option arguments
	 -log format	      format of	debugging information
	 -version	      print version information

       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.

NOTE
       Although	 some  options appear to modify	the file to be identified, the
       identify	command	is strictly read only. For instance, the  crop	option
       crops the in-memory image and then describes the	result.
