       fiascotopnm - Convert compressed FIASCO image to PGM, or PPM

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

       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.

       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.

       -o[name], --output=[name]
               Write decompressed image to the file name.ppm (if PPM) or name.pgm (if PGM).  If name is -,  then  pro-
              duce  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. Other-
              wise, 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 out-
              put 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, --framerate=N
              Set number of frames per second to N. When using this option, the frame rate  specified  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 system.fiascorc for an
              example of the syntax. Options of fiascotopnm  are set by any of the following methods (in the specified

       ?      $HOME/.fiascorc

       ?      command line

       ?      --config=name

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

       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 decom-
       pressed (in 4:2:0 format) at a quarter of its original size; then the image is enlarged  again  by  pixel  dou-
