TIFFCP(1)                                                            TIFFCP(1)



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 shut-
              ter 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) com-
              pression.  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 append-
              ing 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 out-
              put 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 file-
              names 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
