       fiascotopnm - Convert compressed FIASCO image to PGM, or PPM

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

       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.

       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.

       -o[name], --output=[name]
	      Write decompressed image to the file name.ppm (if PPM) or name.pgm  (if  PGM).   If
	      name=-  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).

       -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 de-
	      sired 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 buttons 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, --smooth=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 speci-
	      fied in the FIASCO file is overridden.

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

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

	      1) Global ressource file /etc/system.fiascorc

	      2) $HOME/.fiascorc

	      3) command line

	      4) --config=name

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

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

       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 pos-
	      sible: 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.

	      The systemwide initialization file.
	      The personal initialization file.

	      Save path for image files. Default is "./".
	      Search path for FIASCO files. Default is "./".
