NAME
fiascotopnm - Convert compressed FIASCO image to PGM, or PPM

SYNOPSIS
fiascotopnm [option]... [filename]...

All option names may be abbreviated; for example, --output may be writ-
ten --outp or --ou. For all options an one letter short option is pro-
vided. Mandatory or optional arguments to long options are mandatory or
optional for short options, too. Both short and long options are case
sensitive.

DESCRIPTION
This program is part of Netpbm(1).

fiascotopnm decompresses the named FIASCO files, or the Standard Input
if no file is named, and writes the images as PGM, or PPM files, depend-
ing on whether the FIASCO image is black and white or color.

OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see ]8;;index.html#commonoptions\ Common Options]8;;\ ), fiascotopnm recognizes the
following command line options:

-o[name], --output=[name]
Write decompressed image to the file name.ppm (if PPM) or
name.pgm (if PGM). If name is -, then produce the image file on
the standard output. The optional argument name 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 name.N.ppm where N is the frame number (of the form 00..0 -
99..9); output on the standard output is not possible with video
streams.

If name is a relative path and the environment variable FI-
ASCO_IMAGES 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).

-z, --fast
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.

-d, --double
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.

-p, --panel
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 but-
tons work in the usual way.

-m N, --magnify=N
Set magnification of the decompressed image. Positive values en-
large and negative values reduce the image width and height by a
factor of 2^|N|.

-s N, --smoothing=N
Smooth decompressed image(s) along the partitioning borders by
the given amount N. N is 1 (minimum) to 100 (maximum); default is
70. When N=0, then the smoothing amount specified in the FIASCO
file is used (defined by the FIASCO coder).

-F N, --fps=N
Set number of frames per second to N. When using this option, the
frame rate specified in the FIASCO file is overridden.

--verbose=N
Set verbose of fiascotopnm to N.

-v, --version
Print fiascotopnm version number, then exit.

-f name, --config=name
Load parameter file name to initialize the options of fiasco-
topnm. See file system.fiascorc for an example of the syntax.
Options of fiascotopnm are set by any of the following methods
(in the specified order):

• Global resource file /etc/system.fiascorc

• $HOME/.fiascorc

• command line

• --config=name

-h, --info
Print brief help, then exit.

-H, --help
Print detailed help, then exit.

EXAMPLES
fiascotopnm foo.wfa >foo.ppm

Decompress the FIASCO file "foo.wfa" and store it as "foo.ppm".

fiascotopnm -o foo1.wfa foo2.wfa

Decompress the FIASCO files "foo1.wfa" and "foo2.wfa" and write the
frames to the image files "foo1.wfa.ppm" and "foo2.wfa.ppm".

fiascotopnm -oimage foo1.wfa

Decompress the FIASCO file "foo1.wfa" and write all 15 frames to the im-
age files "image.00.ppm", ... , "image.14.ppm".

fiascotopnm --fast --magnify=-1 --double video.wfa >stream.ppm

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 quar-
ter of its original size; then the image is enlarged again by pixel dou-
bling.

FILES
/etc/system.fiascorc
The systemwide initialization file.

$HOME/.fiascorc
The personal initialization file.

ENVIRONMENT
FIASCO_IMAGES
Save path for image files. Default is "./".
