NAME

tiffutil − manipulates tiff files

SYNOPSIS

tiffutil <option> [<arguments>] [-out <outfile>]

DESCRIPTION

tiffutil lets you manipulate TIFF files. The list of options (also available by running the program without any options) follows:

tiffutil -none      infile                  [-out outfile]
         -lzw       infile                  [-out outfile]
         -lzwdiff   infile                  [-out outfile]
         -packbits  infile                  [-out outfile]
         -cat       infile1 [infile2 ...]   [-out outfile]
         -extract   num infile              [-out outfile]
         -fix       infile                  [-out outfile]
         -info      infile0

-none, -lzw, -lzwdiff, and -packbits options specify the compression format to be applied to the images in the TIFF file.  -none specifies no compression; -packbits specifies PackBits compression; -lzw is the standard Lempel-Ziv & Welch compression (no prediction scheme); -lzwdiff is LZW with horizontal differencing. 

-cat allows combining multiple TIFF files into one.  The images are copied without any change in tag values. 

-extract allows extracting an individual image from a TIFF file; specify num = 0 for the first image in the file. 

-fix fixes TIFF monochrome images with alpha generated by the 1.0 NeXT software. (These images work with 2.0; however, their photometric value is 5, which conflicts with the post-5.0 TIFF standard photometric value of 5, assigned to CMYK color images.) 

-info dumps information about TIFF images. 

For all of the options except for -info, the output goes to "out.tiff" unless an output file name is specified after a -out keyword.  This keyword and the file must be the last items on the command line. -info writes the output to the standard output. 

If there are multiple images in a TIFF file the specified operation will be performed on all of them.
