NAME

6       fiascotopnm - Convert compressed FIASCO image to PGM, or PPM
7

SYNOPSIS

10       fiascotopnm [option]...  [filename]...
11
12       All option names may be abbreviated; for example, --output may be writ‐
13       ten --outp or --ou. For all options an one letter short option is  pro‐
14       vided. Mandatory or optional arguments to long options are mandatory or
15       optional for short options, too. Both short and long options  are  case
16       sensitive.

DESCRIPTION

21       This program is part of Netpbm(1).
22
23       fiascotopnm  decompresses the named FIASCO files, or the Standard Input
24       if no file is named, and writes the images as PGM, or  PPM  files,  de‐
25       pending on whether the FIASCO image is black and white or color.

OPTIONS

29       In  addition  to  the options common to all programs based on libnetpbm
30       (most notably -quiet, see
31        Common Options ⟨index.html#commonoptions⟩  ),  fiascotopnm  recognizes
32       the following command line options:
33
34
35
36       -o[name], --output=[name]
37               Write  decompressed  image  to  the  file  name.ppm (if PPM) or
38              name.pgm (if PGM).  If name is -, then produce the image file on
39              the  standard output. The optional argument name can be omitted,
40              then the input filename is used as basename with the suffix .ppm
41              or  .pgm. In case of video streams, the frames are stored in the
42              files name.N.ppm where N is the frame number (of the form  00..0
43              -  99..9);  output  on  the standard output is not possible with
44              video streams.
45
46               If name is a relative path and  the  environment  variable  FI‐
47              ASCO_IMAGES is a (colon-separated) list of directories, then the
48              output file(s) are written to the first (writable) directory  of
49              this list. Otherwise, the current directory is used to store the
50              output file(s).
51
52
53       -r, --fast
54              Decompress images in the 4:2:0 format; i.e., each chroma channel
55              is decompressed to an image of halved width and height. Use this
56              option on slow machines when  the  desired  frame  rate  is  not
57              achieved; the output quality is only slightly decreased.
58
59
60       -d, --double
61              Double  the  size of the X11 window both in width and height; no
62              pixel interpolation is used, each pixel is just replaced by four
63              identical pixels.
64
65
66       -p, --panel
67              Show  a panel with play, stop, pause, record and exit buttons to
68              control the display of videos. When pressing the record  button,
69              all frames are decompressed and stored in memory. The other but‐
70              tons work in the usual way.
71
72
73       -m N, --magnify=N
74              Set magnification of the decompressed image. Positive values en‐
75              large and negative values reduce the image width and height by a
76              factor of 2^|N|.
77
78
79       -s N, --smoothing=N
80              Smooth decompressed image(s) along the partitioning  borders  by
81              the  given  amount N. N is 1 (minimum) to 100 (maximum); default
82              is 70. When N=0, then the smoothing amount specified in the  FI‐
83              ASCO file is used (defined by the FIASCO coder).
84
85
86       -F N, --framerate=N
87              Set  number  of  frames per second to N. When using this option,
88              the frame rate specified in the FIASCO file is overridden.
89
90
91       --verbose=N
92              Set verbose of fiascotopnm to N.
93
94
95       -v, --version
96              Print fiascotopnm version number, then exit.
97
98
99       -f name, --config=name
100              Load parameter file name to initialize the  options  of  fiasco‐
101              topnm.   See  file system.fiascorc for an example of the syntax.
102              Options of fiascotopnm  are set by any of the following  methods
103              (in the specified order):
104
105
106
107       •      Global ressource file /etc/system.fiascorc
108
109
110       •      $HOME/.fiascorc
111
112
113       •      command line
114
115
116       •      --config=name
117
118
119
120       -h, --help
121              Print help, then exit.

EXAMPLES

128       fiascotopnm foo.wfa >foo.ppm
129
130
131       Decompress the FIASCO file "foo.wfa" and store it as "foo.ppm".
132
133       fiascotopnm -o foo1.wfa foo2.wfa
134
135
136       Decompress  the  FIASCO  files  "foo1.wfa" and "foo2.wfa" and write the
137       frames to the image files "foo1.wfa.ppm" and "foo2.wfa.ppm".
138
139       fiascotopnm -oimage foo1.wfa
140
141
142       Decompress the FIASCO file "foo1.wfa" and write all 15  frames  to  the
143       image files "image.00.ppm", ... , "image.14.ppm".
144
145       fiascotopnm --fast --magnify=-1 --double video.wfa >stream.ppm
146
147
148       Decompress  the FIASCO file "video.wfa".  The decompression speed is as
149       fast as possible: the image is decompressed  (in  4:2:0  format)  at  a
150       quarter of its original size; then the image is enlarged again by pixel
151       doubling.
