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
       -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 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 compres-
	      sion, jpeg for baseline JPEG compression, 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 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 compression can be specified together with  a  predictor  value.   A	predictor
	      value  of  2 causes each scanline of the output image to undergo horizontal differ-
	      encing before it is encoded; a value of 1 forces each scanline to be encoded  with-
	      out  differencing.   LZW-specific  options are specified by appending a ``:''-sepa-
	      rated list to the ``lzw'' option; e.g.  -c lzw:2 for LZW compression with  horizon-
	      tal 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.  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.

       -l     Specify the length of a tile (in pixels).  tiffcp attempts to set the  tile  dimen-
	      sions 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.

       -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, tiffcp attempts to set the rows/strip that no more than 8  kilo-
	      bytes of data appear in a strip.

       -s     Force  the  output  file	to  be written with data organized in strips (rather than
	      tiles).

       -t     Force the output file to be written wtih	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  dimen-
	      sions  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  immedi-
	      ately  following	will  disable the special meaning of the ',' entirely.	See exam-
	      ples.

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 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
