TIFFCP(1)TIFFCP(1)NAMEtiffcp - copy (and possibly convert) a TIFF file
SYNOPSIStiffcp [ options ] src1.tif ... srcN.tif dst.tif
DESCRIPTIONtiffcp 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 direc
tory in the output file.
tiffcp can be used to reorganize the storage characteris
tics of data in a file, but it is explicitly intended to
not alter or convert the image data content in any way.
OPTIONS-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 typlically 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 uncom
pressed 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, jpeg for baseline JPEG compres
sion, zip for Deflate compression, g3 for CCITT
Group 3 (T.4) compression, and g4 for CCITT Group 4
(T.6) 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 algo
rithms 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 bound
ary. 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 compression can be specified together with a
predictor value. A predictor value of 2 causes
each scanline of the output image to undergo hori
zontal differencing before it is encoded; a value
of 1 forces each scanline to be encoded without
differencing. 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.
-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. Specify
ing -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.
-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 read
ing images.
-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. Speci
fying -p contig will force data to be written with
multi-sample data packed together, while -p sepa
rate 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, tiffcp attempts to set the rows/strip that
no more than 8 kilobytes of data appear in a strip.
-s Force the output file to be written with data orga
nized in strips (rather than tiles).
-t Force the output file to be written wtih data orga
nized 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.
-,={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.
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
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 decom
pressing) 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
