identify-im6.q16(1)                General Commands Manual               identify-im6.q16(1)

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

SYNOPSIS
       identify-im6.q16 [options] input-file

OVERVIEW
       The  identify-im6.q16  program  is  a  member of the ImageMagick-ims6.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 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.

         -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
         -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  com‐
       mand  is  strictly read only. For instance, the crop option crops the in-memory image
       and then describes the result.

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.
