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 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 compression, 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 differencing before it is
              encoded; a value of 1 forces each scanline to be encoded without
              differencing.  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.

       -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.

       -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 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.

       -,=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
