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  compres-
       sion schemes.

       By  default,  tiffcp will copy all the understood tags in a TIFF direc-
       tory 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  pro-
              cessed.   This  can be used to remove a noise bias from a set of
              images.  This bias image is typically an image of noise the cam-
              era 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 compres-
              sion, 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 compres-
              sion.  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 scan-
              line 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  avail-
              able).

       -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 spe-
              cial 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 fol-
       lows:
              tiffcp -c none -,=% -b CCD,X.tif CCD,X%1%.tif result.tif
