       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, 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.

       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.
