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

SYNOPSIS
       magick-im7.q16 identify [options] input-file

OVERVIEW
       The  identify-im7.q16 program is a member of the ImageMagick-ims7.q16(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 re‐
       turned 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.

	 -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 number.  To specify a particular image format, pre‐
       cede 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 in‐
       stance, the crop option crops the in-memory image and then describes the result.
