6 fiascotopnm - Convert compressed FIASCO image to PGM, or PPM
7
8
10 fiascotopnm [option]... [filename]...
11
12
14 This program is part of Netpbm(1).
15
16 fiascotopnm decompresses the named FIASCO files, or the Standard Input
17 if no file is named, and writes the images as PGM, or PPM files,
18 depending on whether the FIASCO image is black and white or color.
19
20
22 All option names may be abbreviated; for example, --output may be writ‐
23 ten --outp or --ou. For all options an one letter short option is pro‐
24 vided. Mandatory or optional arguments to long options are mandatory or
25 optional for short options, too. Both short and long options are case
26 sensitive.
27
28
29
30 -o[name], --output=[name]
31 Write decompressed image to the file name.ppm (if PPM) or
32 name.pgm (if PGM). If name is -, then produce the image file on
33 the standard output. The optional argument name can be omitted,
34 then the input filename is used as basename with the suffix .ppm
35 or .pgm. In case of video streams, the frames are stored in the
36 files name.N.ppm where N is the frame number (of the form 00..0
37 - 99..9); output on the standard output is not possible with
38 video streams.
39
40 If name is a relative path and the environment variable
41 FIASCO_IMAGES is a (colon-separated) list of directories, then
42 the output file(s) are written to the first (writable) directory
43 of this list. Otherwise, the current directory is used to store
44 the output file(s).
45
46
47 -z, --fast
48 Decompress images in the 4:2:0 format; i.e., each chroma channel
49 is decompressed to an image of halved width and height. Use this
50 option on slow machines when the desired frame rate is not
51 achieved; the output quality is only slightly decreased.
52
53
54 -d, --double
55 Double the size of the X11 window both in width and height; no
56 pixel interpolation is used, each pixel is just replaced by four
57 identical pixels.
58
59
60 -p, --panel
61 Show a panel with play, stop, pause, record and exit buttons to
62 control the display of videos. When pressing the record button,
63 all frames are decompressed and stored in memory. The other but‐
64 tons work in the usual way.
65
66
67 -m N, --magnify=N
68 Set magnification of the decompressed image. Positive values
69 enlarge and negative values reduce the image width and height by
70 a factor of 2^|N|.
71
72
73 -s N, --smooth=N
74 Smooth decompressed image(s) along the partitioning borders by
75 the given amount N. N is 1 (minimum) to 100 (maximum); default
76 is 70. When N=0, then the smoothing amount specified in the
77 FIASCO file is used (defined by the FIASCO coder).
78
79
80 -F N, --fps=N
81 Set number of frames per second to N. When using this option,
82 the frame rate specified in the FIASCO file is overridden.
83
84
85 -v, --version
86 Print fiascotopnm version number, then exit.
87
88
89 -f name, --config=name
90 Load parameter file name to initialize the options of fiasco‐
91 topnm. See file system.fiascorc for an example of the syntax.
92 Options of fiascotopnm are set by any of the following methods
93 (in the specified order):

122 fiascotopnm foo.wfa >foo.ppm
123
124 Decompress the FIASCO file 'foo.wfa' and store it as 'foo.ppm'.
125
126 fiascotopnm -o foo1.wfa foo2.wfa
127
128 Decompress the FIASCO files 'foo1.wfa' and 'foo2.wfa' and write the
129 frames to the image files 'foo1.wfa.ppm' and 'foo2.wfa.ppm'.
130
131 fiascotopnm -oimage foo1.wfa
132
133 Decompress the FIASCO file 'foo1.wfa' and write all 15 frames to the
134 image files 'image.00.ppm', ... , 'image.14.ppm'.
135
136 fiascotopnm --fast --magnify=-1 --double video.wfa >stream.ppm
137
138 Decompress the FIASCO file 'video.wfa'. The decompression speed is as
139 fast as possible: the image is decompressed (in 4:2:0 format) at a
140 quarter of its original size; then the image is enlarged again by pixel
141 doubling.
142
143
145 /etc/system.fiascorc
146 The systemwide initialization file.
147
148
149 $HOME/.fiascorc
150 The personal initialization file.
