tiffset - set or unset a field in a TIFF header

Tiffset sets the value of a TIFF header to a specified value or removes an existing setting.

       The following example sets the image description tag (270) of a.tif to the contents of the file descrip:
              tiffset -sf 270 descrip a.tif

       The following example sets the artist tag (315) of a.tif to the string ``Anonymous'':
              tiffset -s 315 Anonymous a.tif

       This example sets the resolution of the file a.tif to 300 dpi:
              tiffset -s 296 2 a.tif
              tiffset -s 282 300.0 a.tif
              tiffset -s 283 300.0 a.tif

       Set the photometric interpretation of the third page of a.tif to min-is-black (ie. inverts it):
              tiffset -d 2 -s 262 1 a.tif
