NAME

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

SYNOPSIS

       identify-im6.q16hdri [options] input-file

OVERVIEW

       The  identify-im6.q16hdri  program  is  a  member  of the ImageMagick-ims6.q16hdri(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.

       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, 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.
