RedHat 9 (Linux i386) - man page for tiffsv (redhat section 1)

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	(PlanarConfigura-
       tion=1),  compressed  with the Lempel-Ziv & Welch algorithm (Compression=5), and with each
       strip no more than 8 kilobytes.	These characteristics can  be  overriden,  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 differ-
	      encing before it is encoded; a value of 1 forces each scanline to be encoded  with-
	      out  differencing.   LZW-specific  options are specified by appending a ``:''-sepa-
	      rated list to the ``lzw'' option; e.g.  -c lzw:2 for LZW compression with  horizon-
	      tal 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 kilo-
	      bytes 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.
