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.

	 -virtual-pixel method
			      virtual pixel access method

       Image Operators:
	 -negate	      replace each pixel with its complementary color

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