NAME
       tiffsv - save an image from the framebuffer in a TIFF file (Silicon
       Graphics version)

SYNOPSIS
       tiffsv [ options ] output.tif [ x1 x2 y1 y2 ]

DESCRIPTION
       tiffsv saves all or part of the framebuffer in a file using the Tag
       Image File Format, Revision 6.0.  By default, the image is saved with
       data samples packed (PlanarConfiguration=1), compressed with the
       Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no
       more than 8 kilobytes.  These characteristics can be overridden, or
       explicitly specified with the options described below.

OPTIONS
       -b     Save the image as a greyscale image as if it were processed by
              tiff2bw(1).  This option is included for compatibility with the
              standard scrsave(6D) program.

       -c     Specify the compression to use for data written to the output
              file: none for no compression, packbits for PackBits
              compression, jpeg for baseline JPEG compression, zip for Deflate
              compression, and lzw for Lempel-Ziv & Welch compression
              (default).

              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.

       -p     Specify the planar configuration to use in writing image data.
              By default, tiffsv will create a new file with the data samples
              packed contiguously.  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, tiffsv attempts to set
              the rows/strip that no more than 8 kilobytes of data appear in a
              strip.

NOTE
       Except for the use of TIFF, this program is equivalent to the standard
       scrsave program.  This means, for example, that you can use it in
       conjunction with the standard icut program simply by creating a link
       called scrsave, or by creating a shell script called scrsave that
       invokes tiffgt with the appropriate options.

BUGS
       If data are saved compressed and in separate planes, then the rows in
       each strip is silently set to one to avoid limitations in the
       libtiff(3TIFF) library.
