All option names may be abbreviated; for example, --output may be written --outp or --ou. For all options an one let- ter short option is provided. Mandatory or optional argu- ments to long options are mandatory or optional for short options, too. Both short and long options are case sensi- tive.
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 file- name 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).
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 de- creased.
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.
Show a panel with play, stop, pause, record and ex- it buttons to control the display of videos. When pressing the record button, all frames are decom- pressed and stored in memory. The other buttons work in the usual way.
-m N, --magnify=N
Set magnification of the decompressed image. Posi- tive 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.
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 speci- fied order):
1) Global ressource file /etc/system.fiascorc
3) command line
Print brief help, then exit.
