       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 produce the image file on the standard output. The optional argu-
	      ment name can be omitted, then the input filename is used as basename with the suf-
	      fix  .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 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, --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 speci-
	      fied in the FIASCO file is overridden.

	      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 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):

       o      Global ressource file /etc/system.fiascorc

       o      $HOME/.fiascorc

       o      command line

       o      --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', ... , '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 './'.
