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,
       depending 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
	      FIASCO_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).

       -r, --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
	      enlarge 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, --framerate=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 ressource file /etc/system.fiascorc

       ·      $HOME/.fiascorc

       ·      command line

       ·      --config=name

       -h, --help
	      Print 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 './'.
