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 -i Ignore non-fatal read errors and continue processing of the
74 input file.
75 -l Specify the length of a tile (in pixels). tiffcp attempts to
77 set the tile dimensions so that no more than 8 kilobytes of data
78 appear in a tile.
79 -L Force output to be written with Little-Endian byte order. This
81 option only has an effect when the output file is created or
82 overwritten and not when it is appended to.
83 -M Suppress the use of memory-mapped files when reading images.
85 -p Specify the planar configuration to use in writing image data
87 that has one 8-bit sample per pixel. By default, tiffcp will
88 create a new file with the same planar configuration as the
89 original. Specifying -p contig will force data to be written
90 with multi-sample data packed together, while -p separate will
91 force samples to be written in separate planes.
92 -r Specify the number of rows (scanlines) in each strip of data
94 written to the output file. By default (or when value 0 is
95 specified), tiffcp attempts to set the rows/strip that no more
96 than 8 kilobytes of data appear in a strip. If you specify spe‐
97 cial value -1 it will results in infinite number of the rows per
98 strip. The entire image will be the one strip in that case.
99 -s Force the output file to be written with data organized in
101 strips (rather than tiles).
102 -t Force the output file to be written with data organized in tiles
104 (rather than strips). options can be used to force the resultant
105 image to be written as strips or tiles of data, respectively.
106 -w Specify the width of a tile (in pixels). tiffcp attempts to set
108 the tile dimensions so that no more than 8 kilobytes of data
109 appear in a tile. tiffcp attempts to set the tile dimensions so
110 that no more than 8 kilobytes of data appear in a tile.
111 -x Force the output file to be written with PAGENUMBER value in
113 sequence.
114 -,=character
116 substitute character for `,' in parsing image directory indices
117 in files. This is necessary if filenames contain commas. Note
118 that -,= with whitespace immediately following will disable the
119 special meaning of the `,' entirely. See examples.
120
122 The following concatenates two files and writes the result using LZW
123 encoding:
124 tiffcp -c lzw a.tif b.tif result.tif
125 To convert a G3 1d-encoded TIFF to a single strip of G4-encoded data
127 the following might be used:
128 tiffcp -c g4 -r 10000 g3.tif g4.tif
129 (1000 is just a number that is larger than the number of rows in the
130 source file.)
131 To extract a selected set of images from a multi-image TIFF file, the
133 file name may be immediately followed by a `,' separated list of image
134 directory indices. The first image is always in directory 0. Thus, to
135 copy the 1st and 3rd images of image file ``album.tif'' to
136 ``result.tif'':
137 tiffcp album.tif,0,2 result.tif
138 A trailing comma denotes remaining images in sequence. The following
140 command will copy all image with except the first one:
141 tiffcp album.tif,1, result.tif
142 Given file ``CCD.tif'' whose first image is a noise bias followed by
144 images which include that bias, subtract the noise from all those
145 images following it (while decompressing) with the command:
146 tiffcp -c none -b CCD.tif CCD.tif,1, result.tif
147 If the file above were named ``CCD,X.tif'', the -,= option would be
149 required to correctly parse this filename with image numbers, as fol‐
150 lows:
151 tiffcp -c none -,=% -b CCD,X.tif CCD,X%1%.tif result.tif
