NAME
tiffcp - copy (and possibly convert) a TIFF file
SYNOPSIS
tiffcp [ options ] src1.tif ... srcN.tif dst.tif
DESCRIPTION
tiffcp combines one or more files created according to the Tag Image File Format, Revision 6.0 into a
single TIFF file. Because the output file may be compressed using a different algorithm than the input
files, tiffcp is most often used to convert between different compression schemes.
By default, tiffcp will copy all the understood tags in a TIFF directory of an input file to the
associated directory in the output file.
tiffcp can be used to reorganize the storage characteristics of data in a file, but it is explicitly
intended to not alter or convert the image data content in any way.
OPTIONS
-a Append to an existing output file instead of overwriting it.
-b image
subtract the following monochrome image from all others processed. This can be used to remove a
noise bias from a set of images. This bias image is typically an image of noise the camera saw
with its shutter closed.
-B Force output to be written with Big-Endian byte order. This option only has an effect when the
output file is created or overwritten and not when it is appended to.
-C Suppress the use of ``strip chopping'' when reading images that have a single strip/tile of
uncompressed data.
-c Specify the compression to use for data written to the output file: none for no compression,
packbits for PackBits compression, lzw for Lempel-Ziv & Welch compression, zip for Deflate
compression, lzma for LZMA2 compression, jpeg for baseline JPEG compression, g3 for CCITT Group 3
(T.4) compression, g4 for CCITT Group 4 (T.6) compression, or sgilog for SGILOG compression. By
default tiffcp will compress data according to the value of the Compression tag found in the
source file.
The CCITT Group 3 and Group 4 compression algorithms can only be used with bilevel data.
Group 3 compression can be specified together with several T.4-specific options: 1d for
1-dimensional encoding, 2d for 2-dimensional encoding, and fill to force each encoded scanline to
be zero-filled so that the terminating EOL code lies on a byte boundary. Group 3-specific options
are specified by appending a ``:''-separated list to the ``g3'' option; e.g. -c g3:2d:fill to get
2D-encoded data with byte-aligned EOL codes.
LZW, Deflate and LZMA2 compression can be specified together with a predictor value. A predictor
value of 2 causes each scanline of the output image to undergo horizontal differencing before it
is encoded; a value of 1 forces each scanline to be encoded without differencing. A value 3 is for
floating point predictor which you can use if the encoded data are in floating point format. LZW-
specific options are specified by appending a ``:''-separated list to the ``lzw'' option; e.g. -c
lzw:2 for LZW compression with horizontal differencing.
Deflate and LZMA2 encoders support various compression levels (or encoder presets) set as
character ``p'' and a preset number. ``p1'' is the fastest one with the worst compression ratio
and ``p9'' is the slowest but with the best possible ratio; e.g. -c zip:3:p9 for Deflate encoding
with maximum compression level and floating point predictor.
For the Deflate codec, and in a libtiff build with libdeflate enabled, ``p12`` is actually the
maximum level.
For the Deflate codec, and in a libtiff build with libdeflate enabled, ``s0`` can be used to
require zlib to be used, and ``s1`` for libdeflate (defaults to libdeflate when it is available).
-f Specify the bit fill order to use in writing output data. By default, tiffcp will create a new
file with the same fill order as the original. Specifying -f lsb2msb will force data to be
written with the FillOrder tag set to LSB2MSB, while -f msb2lsb will force data to be written with
the FillOrder tag set to MSB2LSB.
-i Ignore non-fatal read errors and continue processing of the input file.
-l Specify the length of a tile (in pixels). tiffcp attempts to set the tile dimensions so that no
more than 8 kilobytes of data appear in a tile.
-L Force output to be written with Little-Endian byte order. This option only has an effect when the
output file is created or overwritten and not when it is appended to.
-M Suppress the use of memory-mapped files when reading images.
-o offset
Set initial directory offset.
-p Specify the planar configuration to use in writing image data that has one 8-bit sample per pixel.
By default, tiffcp will create a new file with the same planar configuration as the original.
Specifying -p contig will force data to be written with multi-sample data packed together, while
-p separate will force samples to be written in separate planes.
-r Specify the number of rows (scanlines) in each strip of data written to the output file. By
default (or when value 0 is specified), tiffcp attempts to set the rows/strip that no more than 8
kilobytes of data appear in a strip. If you specify special value -1 it will results in infinite
number of the rows per strip. The entire image will be the one strip in that case.
-s Force the output file to be written with data organized in strips (rather than tiles).
-t Force the output file to be written with data organized in tiles (rather than strips). options can
be used to force the resultant image to be written as strips or tiles of data, respectively.
-w Specify the width of a tile (in pixels). tiffcp attempts to set the tile dimensions so that no
more than 8 kilobytes of data appear in a tile. tiffcp attempts to set the tile dimensions so
that no more than 8 kilobytes of data appear in a tile.
-x Force the output file to be written with PAGENUMBER value in sequence.
-8 Write BigTIFF instead of classic TIFF format.
-,=character
substitute character for `,' in parsing image directory indices in files. This is necessary if
filenames contain commas. Note that -,= with whitespace immediately following will disable the
special meaning of the `,' entirely. See examples.
-m size
Set maximum memory allocation size (in MiB). The default is 256MiB. Set to 0 to disable the
limit.
EXAMPLES
The following concatenates two files and writes the result using LZW encoding:
tiffcp -c lzw a.tif b.tif result.tif
To convert a G3 1d-encoded TIFF to a single strip of G4-encoded data the following might be used:
tiffcp -c g4 -r 10000 g3.tif g4.tif
(1000 is just a number that is larger than the number of rows in the source file.)
To extract a selected set of images from a multi-image TIFF file, the file name may be immediately
followed by a `,' separated list of image directory indices. The first image is always in directory 0.
Thus, to copy the 1st and 3rd images of image file ``album.tif'' to ``result.tif'':
tiffcp album.tif,0,2 result.tif
A trailing comma denotes remaining images in sequence. The following command will copy all image with
except the first one:
tiffcp album.tif,1, result.tif
Given file ``CCD.tif'' whose first image is a noise bias followed by images which include that bias,
subtract the noise from all those images following it (while decompressing) with the command:
tiffcp -c none -b CCD.tif CCD.tif,1, result.tif
If the file above were named ``CCD,X.tif'', the -,= option would be required to correctly parse this
filename with image numbers, as follows:
tiffcp -c none -,=% -b CCD,X.tif CCD,X%1%.tif result.tif
