TIFFUTIL(1)               BSD General Commands Manual              TIFFUTIL(1)

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]
              -packbits         infile                  [-out outfile]
              -cat              infile1 [infile2 ...]   [-out outfile]
              -catnosizecheck   infile1 [infile2 ...]   [-out outfile]
              -cathidpicheck    infile1 [infile2 ...]   [-out outfile]
              -extract          num infile              [-out outfile]
              -info             infile
              -verboseinfo      infile
              -dump             infile

     -none, -lzw, 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 specifies
     standard Lempel-Ziv & Welch compression (no prediction scheme).

     -cat allows combining multiple TIFF files into one.  The images are copied without any change in tag
     values. If the real sizes (pixel size divided by dpi) of the images being combined are not the same, a
     warning will be generated. This makes sure that NSImage can successfully choose the right size image
     out of the generated TIFF file. Use -catnosizecheck to bypass the size check.

     -cathidpicheck can be used to write an output file conforming to Apple's guidelines for resolution
     independent bitmap images, and will generate warnings if the supplied images do not have the recom-mended recommended
     mended size relationship. For best results, ensure that the larger file has a filename of the form
     <basename>@2x.png.

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

     -info prints information about TIFF images. -verboseinfo is the same, except most of the tables are
     displayed in full. -dump simply lists all of the tags in the file without trying to interpret them; it
     is handy when trying to figure out why a TIFF file won't load or display properly.

     For options which write images out, the output goes to "out.tiff" unless an output file name is speci-fied specified
     fied after a -out keyword.  This keyword and the file must be the last items on the command line.
     -info, -verboseinfo, and -dump write their output to the standard output.

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

     SECURITY NOTE: This version of tiffutil SHOULD NOT be used with untrusted files.
