    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   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) 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 compression can be specified together with a  pred-
              ictor  value.  A predictor value of 2 causes each scan-
              line of the output image  to  undergo  horizontal  dif-
              ferencing  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 Fil-
              lOrder 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 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 sam-
              ples 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
              kilobytes 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 dimensions so that no more
              than 8 kilobytes of data appear in a tile.
    
    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.)
