<H2>DESCRIPTION</H2>
|
||
|
|
|
||
|
|
<I>tiffsv</I>
|
||
|
|
|
||
|
|
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 (<I>PlanarConfiguration</I>=1),
|
||
|
|
|
||
|
|
compressed with the Lempel-Ziv & Welch algorithm (<I>Compression</I>=5),
|
||
|
|
|
||
|
|
and with each strip no more than 8 kilobytes.
|
||
|
|
These characteristics can be overriden, or explicitly specified
|
||
|
|
with the options described below.

Save the image as a greyscale image
|
||
|
|
as if it were processed by
|
||
|
|
<I><A HREF="tiff2bw+1.html">tiff2bw</A></I>(1).
|
||
|
|
|
||
|
|
This option is included for compatibility with the standard
|

|
|
<I><A HREF="scrsave+6d">scrsave</A></I>(6D)
|
||
|
|
|

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>jpeg</B>
|
||
|
|
|
||
|
|
for baseline JPEG compression,
|
||
|
|
<B>zip</B>
|
||
|
|
|
||
|
|
for Deflate compression,
|
||
|
|
and
|

|
|
<B>lzw</B>
|

for Lempel-Ziv & Welch compression (default).
|

<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.

Specify the planar configuration to use in writing image data.
|
||
|
|
By default,
|
||
|
|
<I>tiffsv</I>
|
||
|
|
|
||
|
|
will create a new file with the data samples packed contiguously.
|

Specifying
|
||
|
|
<B>-p contig</B>
|
||
|
|

|
||
|
|
together, while
|
||
|
|
<B>-p separate</B>
|
||
|
|
|
||
|
|
will force samples to be written in separate planes.

<DD>
|
||
|
|
Specify the number of rows (scanlines) in each strip of data
|
||
|
|
written to the output file.
|
||
|
|
By default,
|
||
|
|
<I>tiffsv</I>
|
||
|
|
|
||
|
|
attempts to set the rows/strip
|
||
|
|
that no more than 8 kilobytes of data appear in a strip.

<H2>NOTE</H2>
|
||
|
|
|
||
|
|
Except for the use of
|
||
|
|
<FONT SIZE="-1">TIFF,</FONT>
|
||
|
|
this program is equivalent to the standard
|
||
|
|
<I>scrsave</I>
|
||
|
|
|
||
|
|
program.
|
||
|
|
This means, for example, that you can use it in conjunction with
|
||
|
|
the standard
|
||
|
|
<I>icut</I>
|
||
|
|
|
||
|
|
program simply by creating a link called
|
||
|
|
<I>scrsave</I>,
|
||
|
|
|
||
|
|
or by creating a shell script called
|
||
|
|
<I>scrsave</I>
|
||
|
|
|
||
|
|
that invokes
|
||
|
|
<I>tiffgt</I>
|
||
|
|
|
||
|
|
with the appropriate options.

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
