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
       -a     Append to an existing output file instead of overwriting it

       -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 typically 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,  zip  for  Deflate compression, lzma for LZMA2 compression, jpeg for baseline
	      JPEG 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, Deflate and LZMA2 compression can  be  specified  together  with  a	predictor
	      value.  A  predictor value of 2 causes each scanline 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.

       -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 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.

       -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
	      special  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 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.

       -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.

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 follows:
	      tiffcp -c none -,=% -b CCD,X.tif CCD,X%1%.tif result.tif
