NAME

       tiffset - set a field in a TIFF header

       Tiffset sets the value of a TIFF header to a specified value.

OPTIONS

       -d dirnumber
	      change the current directory (starting at 0).

	      Set the value of the named tag to the value or values specified.

       -sd diroffset
	      change the current directory by offset.

       -sf tagnumber filename
	      Set the value of the tag to the contents of filename.  This option is supported for ASCII tags only.

EXAMPLES

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