.SH NAME
fiascotopnm - Convert compressed FIASCO image to PGM, or PPM
.UN synopsis
.SH SYNOPSIS
\fBfiascotopnm \fP
[\fIoption\fP]...
[\fIfilename\fP]...
.PP
All option names may be abbreviated; for example, --output may be
written --outp or --ou. For all options an one letter short option
is provided. Mandatory or optional arguments to long options are
mandatory or optional for short options, too. Both short and long
options are case sensitive.
.UN description
.SH DESCRIPTION
.PP
This program is part of
.BR "Netpbm" (1)\c
\&.
.PP
\fBfiascotopnm\fP decompresses the named FIASCO files, or the
Standard Input if no file is named, and writes the images as PGM, or
PPM files, depending on whether the FIASCO image is black and white or
color.
.UN options
.SH OPTIONS
.TP
\fB-o\fP[\fIname\fP], \fB--output=\fP[\fIname\fP]
Write decompressed image to the file \fIname\fP.ppm (if PPM) or
\fIname\fP.pgm (if PGM). If \fIname\fP is \fB-\fP, then produce
the image file on the standard output. The optional argument
\fIname\fP can be omitted, then the input filename is used as
basename with the suffix .ppm or .pgm. In case of video streams, the
frames are stored in the files \fIname\fP.\fBN\fP.ppm where \fBN\fP
is the frame number (of the form 00..0 - 99..9); output on the
standard output is not possible with video streams.
.sp
If \fIname\fP is a relative path and the environment variable
\fBFIASCO_IMAGES\fP is a (colon-separated) list of directories, then
the output file(s) are written to the first (writable) directory of
this list. Otherwise, the current directory is used to store the
output file(s).
.TP
\fB-z\fP, \fB--fast\fP
Decompress images in the 4:2:0 format; i.e., each chroma channel is
decompressed to an image of halved width and height. Use this option
on slow machines when the desired frame rate is not achieved; the
output quality is only slightly decreased.
.TP
\fB-d\fP, \fB--double\fP
Double the size of the X11 window both in width and height; no pixel
interpolation is used, each pixel is just replaced by four identical
pixels.
.TP
\fB-p\fP, \fB--panel\fP
Show a panel with play, stop, pause, record and exit buttons to
control the display of videos. When pressing the record button, all
frames are decompressed and stored in memory. The other buttons work
in the usual way.
.TP
\fB-m\fP \fIN\fP, \fB--magnify=\fP\fIN\fP
Set magnification of the decompressed image. Positive values enlarge
and negative values reduce the image width and height by a factor of
2^|\fIN\fP|.
.TP
\fB-s\fP \fIN\fP, \fB--smoothing=\fP\fIN\fP
Smooth decompressed image(s) along the partitioning borders by the
given amount \fIN\fP. \fIN\fP is 1 (minimum) to 100 (maximum); default
is 70. When \fIN\fP=0, then the smoothing amount specified in the
FIASCO file is used (defined by the FIASCO coder).
.TP
\fB-F\fP \fIN\fP, \fB--fps=\fP\fIN\fP
Set number of frames per second to \fIN\fP. When using this option,
the frame rate specified in the FIASCO file is overridden.
.TP
\fB--verbose=\fP\fIN\fP
Set verbose of \fBfiascotopnm\fP to \fIN\fP.
.TP
\fB-v\fP, \fB--version\fP
Print \fBfiascotopnm\fP version number, then exit.
.TP
\fB-f\fP \fIname\fP, \fB--config=\fP\fIname\fP
Load parameter file \fIname\fP to initialize the options of
\fBfiascotopnm\fP. See file \fBsystem.fiascorc\fP for an example of
the syntax. Options of \fBfiascotopnm \fP are set by any of the
following methods (in the specified order):
.IP \(bu
Global ressource file \fB/etc/system.fiascorc\fP
.IP \(bu
$HOME\fB/.fiascorc\fP
.IP \(bu
command line
.IP \(bu
--config=\fIname\fP
.TP
\fB-h\fP, \fB--info\fP
Print brief help, then exit.
.TP
\fB-H\fP, \fB--help\fP
Print detailed help, then exit.
.UN examples
.SH EXAMPLES
.nf
fiascotopnm foo.wfa >foo.ppm
.fi
.PP
Decompress the FIASCO file "foo.wfa" and store it as
"foo.ppm".
.nf
fiascotopnm -o foo1.wfa foo2.wfa
.fi
.PP
Decompress the FIASCO files "foo1.wfa" and
"foo2.wfa" and write the frames to the image files
"foo1.wfa.ppm" and "foo2.wfa.ppm".
.nf
fiascotopnm -oimage foo1.wfa
.fi
.PP
Decompress the FIASCO file "foo1.wfa" and write all 15
frames to the image files "image.00.ppm", ... ,
"image.14.ppm".
.nf
fiascotopnm --fast --magnify=-1 --double video.wfa >stream.ppm
.fi
.PP
Decompress the FIASCO file "video.wfa". The
decompression speed is as fast as possible: the image is decompressed
(in 4:2:0 format) at a quarter of its original size; then the image is
enlarged again by pixel doubling.
.UN files
.SH FILES
.TP
\fB/etc/system.fiascorc\fP

$HOME\fB/.fiascorc\fP
