.TH TIFFSV 1 "September 20, 2005" "libtiff"
|
|
.SH NAME
|
|
tiffsv \- save an image from the framebuffer in a
|
|
.SM TIFF
|
|
file (Silicon Graphics version)
|
|
.SH SYNOPSIS
|
|
.B tiffsv
|
|
[
|
|
.I options
|
|
]
|
|
.I output.tif
|
|
[
|
|
.I "x1 x2 y1 y2"
|
|
]
|
|
.SH DESCRIPTION
|
|
.I 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 (\c
|
|
.IR PlanarConfiguration =1),
|
|
compressed with the Lempel-Ziv & Welch algorithm (\c
|
|
.IR Compression =5),
|
|
and with each strip no more than 8 kilobytes.
|
|
These characteristics can be overridden, or explicitly specified
|
|
with the options described below.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-b
|
|
Save the image as a greyscale image
|
|
as if it were processed by
|
|
.IR tiff2bw (1).
|
|
This option is included for compatibility with the standard
|
|
.IR scrsave (6D)
|
|
program.
|
|
.TP
|
|
.B \-c
|
|
Specify the compression to use for data written to the output file:
|
|
.B none
|
|
for no compression,
|
|
.B packbits
|
|
for PackBits compression,
|
|
.B jpeg
|
|
for baseline JPEG compression,
|
|
.B zip
|
|
for Deflate compression,
|
|
and
|
|
.B lzw
|
|
for Lempel-Ziv & Welch compression (default).
|
|
.IP
|
|
.SM LZW
|
|
compression can be specified together with a
|
|
.I 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.
|
|
.B "\-c lzw:2"
|
|
for
|
|
.SM LZW
|
|
compression with horizontal differencing.
|
|
.TP
|
|
.B \-p
|
|
Specify the planar configuration to use in writing image data.
|
|
By default,
|
|
.I tiffsv
|
|
will create a new file with the data samples packed contiguously.
|
|
Specifying
|
|
.B "\-p contig"
|
|
will force data to be written with multi-sample data packed
|
|
together, while
|
|
.B "\-p separate"
|
|
will force samples to be written in separate planes.
|
|
.TP
|
|
.B \-r
|
|
Specify the number of rows (scanlines) in each strip of data
|
|
written to the output file.
|
|
By default,
|
|
.I tiffsv
|
|
attempts to set the rows/strip
|
|
that no more than 8 kilobytes of data appear in a strip.
|
|
.SH NOTE
|
|
Except for the use of
|
|
.SM TIFF,
|
|
this program is equivalent to the standard
|
|
.I scrsave
|
|
program.
|
|
This means, for example, that you can use it in conjunction with
|
|
the standard
|
|
.IR icut
|
|
program simply by creating a link called
|
|
.IR scrsave ,
|
|
or by creating a shell script called
|
|
.I scrsave
|
|
that invokes
|
|
.I tiffgt
|
|
with the appropriate options.
|
|
.SH 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
|
|
.BR libtiff (3TIFF)
|
|
library.
