TIFFSV(1)                                               TIFFSV(1)

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 (Pla-
       narConfiguration=1),  compressed  with  the  Lempel-Ziv  &
       Welch algorithm (Compression=5), and with  each  strip  no
       more than 8 kilobytes.  These characteristics can be over-
       riden, 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  hori-
              zontal  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 sepa-
              rate 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(3) library.
