TIFFUTIL(1) BSD General Commands Manual TIFFUTIL(1)NAMEtiffutil - manipulates tiff files
SYNOPSIStiffutil <option> [<arguments>] [-out <outfile>]
DESCRIPTIONtiffutil lets you manipulate TIFF files. The list of options (also avail‐
able 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 recommended size rela‐
tionship. 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 specified 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.
