<H2>NAME</H2>
tiffcp - copy (and possibly convert) a
<FONT SIZE="-1">TIFF</FONT>
file
<A NAME="lbAC">&nbsp;</A>
<H2>SYNOPSIS</H2>
<B>tiffcp</B>
[
<I>options</I>
]
<I>src1.tif ... srcN.tif dst.tif</I>
<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>
<I>tiffcp</I>
combines one or more files created according
to the Tag Image File Format, Revision 6.0
into a single
<FONT SIZE="-1">TIFF</FONT>
file.
Because the output file may be compressed using a different
algorithm than the input files,
<I>tiffcp</I>
is most often used to convert between different compression
schemes.
<P>
By default,
<I>tiffcp</I>
will copy all the understood tags in a
<FONT SIZE="-1">TIFF</FONT>
directory of an input
file to the associated directory in the output file.
<P>
<I>tiffcp</I>
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.
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT><B>-B</B>
<DD>
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.
<DT><B>-C</B>
<DD>
Suppress the use of ``strip chopping'' when reading images
that have a single strip/tile of uncompressed data.
<DT><B>-c</B>
<DD>
Specify the compression to use for data written to the output file:
<B>none </B>
for no compression,
<B>packbits</B>
for PackBits compression,
<B>lzw</B>
for Lempel-Ziv &amp; Welch compression,
<B>jpeg</B>
for baseline JPEG compression,
<B>zip</B>
for Deflate compression,
<B>g3</B>
for CCITT Group 3 (T.4) compression,
and
<B>g4</B>
for CCITT Group 4 (T.6) compression.
By default
<I>tiffcp</I>
will compress data according to the value of the
<I>Compression</I>
tag found in the source file.
<DT><DD>
The
<FONT SIZE="-1">CCITT</FONT>
Group 3 and Group 4 compression algorithms can only
be used with bilevel data.
<DT><DD>
Group 3 compression can be specified together with several
T.4-specific options:
<B>1d</B>
for 1-dimensional encoding,
<B>2d</B>
for 2-dimensional encoding,
and
<B>fill</B>
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.
<B>-c g3:2d:fill</B>
to get 2D-encoded data with byte-aligned EOL codes.
<DT><DD>
<FONT SIZE="-1">LZW</FONT>
compression can be specified together with a
<I>predictor</I>
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.
<B>-c lzw:2</B>
for
<FONT SIZE="-1">LZW</FONT>
compression with horizontal differencing.
<DT><B>-f</B>
<DD>
Specify the bit fill order to use in writing output data.
By default,
<I>tiffcp</I>
will create a new file with the same fill order as the original.
Specifying
<B>-f lsb2msb</B>
will force data to be written with the FillOrder tag set to
<FONT SIZE="-1">LSB2MSB,</FONT>
while
<B>-f msb2lsb</B>
will force data to be written with the FillOrder tag set to
<FONT SIZE="-1">MSB2LSB.</FONT>
<DT><B>-l</B>
<DD>
Specify the length of a tile (in pixels).
<I>tiffcp</I>
attempts to set the tile dimensions so
that no more than 8 kilobytes of data appear in a tile.
<DT><B>-L</B>
<DD>
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.
<DT><B>-M</B>
<DD>
Suppress the use of memory-mapped files when reading images.
<DT><B>-p</B>
<DD>
Specify the planar configuration to use in writing image data
that has one 8-bit sample per pixel.
By default,
<I>tiffcp</I>
will create a new file with the same planar configuration as
the original.
Specifying
<B>-p contig</B>
will force data to be written with multi-sample data packed
together, while
<B>-p separate</B>
will force samples to be written in separate planes.
<DT><B>-r</B>
<DD>
Specify the number of rows (scanlines) in each strip of data
written to the output file.
By default,
<I>tiffcp</I>
attempts to set the rows/strip
that no more than 8 kilobytes of data appear in a strip.
<DT><B>-s</B>
<DD>
Force the output file to be written with data organized in strips
(rather than tiles).
<DT><B>-t</B>
<DD>
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.
<DT><B>-w</B>
<DD>
Specify the width of a tile (in pixels).
<I>tiffcp</I>
attempts to set the tile dimensions so
that no more than 8 kilobytes of data appear in a tile.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>EXAMPLES</H2>
The following concatenates two files and writes the result using
<FONT SIZE="-1">LZW</FONT>
encoding:
<DL COMPACT><DT><DD>
<PRE>
tiffcp -c lzw a.tif b.tif result.tif
</PRE>
</DL>
<P>
To convert a G3 1d-encoded
<FONT SIZE="-1">TIFF</FONT>
to a single strip of G4-encoded data the following might be used:
<DL COMPACT><DT><DD>
<PRE>
tiffcp -c g4 -r 10000 g3.tif g4.tif
</PRE>
</DL>
(1000 is just a number that is larger than the number of rows in
the source file.)
