       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  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
              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 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 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 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.


              The systemwide initialization file.
              The personal initialization file.


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