6 tiffcp - copy (and possibly convert) a TIFF file
7
9 tiffcp [ options ] src1.tif ... srcN.tif dst.tif
10
12 tiffcp combines one or more files created according to the Tag Image
13 File Format, Revision 6.0 into a single TIFF file. Because the output
14 file may be compressed using a different algorithm than the input
15 files, tiffcp is most often used to convert between different compres‐
16 sion schemes.
17 By default, tiffcp will copy all the understood tags in a TIFF direc‐
19 tory of an input file to the associated directory in the output file.
20 tiffcp can be used to reorganize the storage characteristics of data in
22 a file, but it is explicitly intended to not alter or convert the image
23 data content in any way.
24
26 -b image
27 subtract the following monochrome image from all others pro‐
28 cessed. This can be used to remove a noise bias from a set of
29 images. This bias image is typically an image of noise the cam‐
30 era saw with its shutter closed.
31 -B Force output to be written with Big-Endian byte order. This
33 option only has an effect when the output file is created or
34 overwritten and not when it is appended to.
35 -C Suppress the use of ``strip chopping'' when reading images that
37 have a single strip/tile of uncompressed data.
38 -c Specify the compression to use for data written to the output
40 file: none for no compression, packbits for PackBits compres‐
41 sion, lzw for Lempel-Ziv & Welch compression, jpeg for baseline
42 JPEG compression, zip for Deflate compression, g3 for CCITT
43 Group 3 (T.4) compression, and g4 for CCITT Group 4 (T.6) com‐
44 pression. By default tiffcp will compress data according to the
45 value of the Compression tag found in the source file.
46 The CCITT Group 3 and Group 4 compression algorithms can only be
48 used with bilevel data.
49 Group 3 compression can be specified together with several
51 T.4-specific options: 1d for 1-dimensional encoding, 2d for
52 2-dimensional encoding, and fill to force each encoded scanline
53 to be zero-filled so that the terminating EOL code lies on a
54 byte boundary. Group 3-specific options are specified by
55 appending a ``:''-separated list to the ``g3'' option; e.g. -c
56 g3:2d:fill to get 2D-encoded data with byte-aligned EOL codes.
57 LZW compression can be specified together with a predictor
59 value. A predictor value of 2 causes each scanline of the out‐
60 put image to undergo horizontal differencing before it is
61 encoded; a value of 1 forces each scanline to be encoded without
62 differencing. LZW-specific options are specified by appending a
63 ``:''-separated list to the ``lzw'' option; e.g. -c lzw:2 for
64 LZW compression with horizontal differencing.
65 -f Specify the bit fill order to use in writing output data. By
67 default, tiffcp will create a new file with the same fill order
68 as the original. Specifying -f lsb2msb will force data to be
69 written with the FillOrder tag set to LSB2MSB, while -f msb2lsb
70 will force data to be written with the FillOrder tag set to
71 MSB2LSB.
72 -l Specify the length of a tile (in pixels). tiffcp attempts to
74 set the tile dimensions so that no more than 8 kilobytes of data
75 appear in a tile.
76 -L Force output to be written with Little-Endian byte order. This
78 option only has an effect when the output file is created or
79 overwritten and not when it is appended to.
80 -M Suppress the use of memory-mapped files when reading images.
82 -p Specify the planar configuration to use in writing image data
84 that has one 8-bit sample per pixel. By default, tiffcp will
85 create a new file with the same planar configuration as the
86 original. Specifying -p contig will force data to be written
87 with multi-sample data packed together, while -p separate will
88 force samples to be written in separate planes.
89 -r Specify the number of rows (scanlines) in each strip of data
91 written to the output file. By default (or when value 0 is
92 specified), tiffcp attempts to set the rows/strip that no more
93 than 8 kilobytes of data appear in a strip. If you specify spe‐
94 cial value -1 it will results in infinite number of the rows per
95 strip. The entire image will be the one strip in that case.
96 -s Force the output file to be written with data organized in
98 strips (rather than tiles).
99 -t Force the output file to be written with data organized in tiles
101 (rather than strips). options can be used to force the resul‐
102 tant image to be written as strips or tiles of data, respec‐
103 tively.
104 -w Specify the width of a tile (in pixels). tiffcp attempts to set
106 the tile dimensions so that no more than 8 kilobytes of data
107 appear in a tile. tiffcp attempts to set the tile dimensions so
108 that no more than 8 kilobytes of data appear in a tile.
109 -,={character}
111 substitute {character} for ',' in parsing image directory
112 indices in files. This is necessary if filenames contain com‐
113 mas. Note that ',=' with whitespace immediately following will
114 disable the special meaning of the ',' entirely. See examples.
115
117 The following concatenates two files and writes the result using LZW
118 encoding:
119 tiffcp -c lzw a.tif b.tif result.tif
120 To convert a G3 1d-encoded TIFF to a single strip of G4-encoded data
122 the following might be used:
123 tiffcp -c g4 -r 10000 g3.tif g4.tif
124 (1000 is just a number that is larger than the number of rows in the
125 source file.)
126 To extract a selected set of images from a multi-image TIFF file, the
128 file name may be immediately followed by a ',' separated list of image
129 directory indices. The first image is always in directory 0. Thus, to
130 copy the 1st and 3rd images of image file "album.tif" to "result.tif":
131 tiffcp album.tif,0,2 result.tif
132 Given file "CCD.tif" whose first image is a noise bias followed by
134 images which include that bias, subtract the noise from all those
135 images following it (while decompressing) with the command:
136 tiffcp -c none -b CCD.tif CCD.tif,1, result.tif
137 If the file above were named "CCD,X.tif", the "-,=" option would be
139 required to correctly parse this filename with image numbers, as fol‐
140 lows:
141 tiffcp -c none -,=% -b CCD,X.tif CCD,X%1%.tif result.tif
