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.

         -monitor             monitor progress
         -ping                efficiently determine image attributes
         -precision value     maximum number of significant digits to print
         -verbose             print detailed information about the image
         -virtual-pixel method
                              virtual pixel access method

       Image Operators:
         -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.
