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,  de-
       pending on whether the FIASCO image is black and	white or color.

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  FI-
	      ASCO 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):

       o      Global ressource file /etc/system.fiascorc

       o      $HOME/.fiascorc

       o      command line

       o      --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
       image 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
       quarter of its original size; then the image is enlarged	again by pixel
       doubling.

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

       $HOME/.fiascorc
	      The personal initialization file.

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

       FIASCO_DATA
	      Search path for FIASCO files. Default is "./".
