6 fiascotopnm - Convert compressed FIASCO image to PGM, or PPM
7
10 fiascotopnm [option]... [filename]...
11 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.
17
21 This program is part of Netpbm(1).
22 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,
25 depending on whether the FIASCO image is black and white or color.
26
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 -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 If name is a relative path and the environment variable
47 FIASCO_IMAGES is a (colon-separated) list of directories, then
48 the output file(s) are written to the first (writable) directory
49 of this list. Otherwise, the current directory is used to store
50 the output file(s).
51 -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 -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 -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 -m N, --magnify=N
74 Set magnification of the decompressed image. Positive values
75 enlarge and negative values reduce the image width and height by
76 a factor of 2^|N|.
77 -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
83 FIASCO file is used (defined by the FIASCO coder).
84 -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 --verbose=N
92 Set verbose of fiascotopnm to N.
93 -v, --version
96 Print fiascotopnm version number, then exit.
97 -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 · Global ressource file /etc/system.fiascorc
108 · $HOME/.fiascorc
111 · command line
114 · --config=name
117 -h, --help
121 Print help, then exit.
122
128 fiascotopnm foo.wfa >foo.ppm
129 Decompress the FIASCO file "foo.wfa" and store it as "foo.ppm".
131 fiascotopnm -o foo1.wfa foo2.wfa
133 Decompress the FIASCO files "foo1.wfa" and "foo2.wfa" and write the
135 frames to the image files "foo1.wfa.ppm" and "foo2.wfa.ppm".
136 fiascotopnm -oimage foo1.wfa
138 Decompress the FIASCO file "foo1.wfa" and write all 15 frames to the
140 image files "image.00.ppm", ... , "image.14.ppm".
141 fiascotopnm --fast --magnify=-1 --double video.wfa >stream.ppm
143 Decompress the FIASCO file "video.wfa". The decompression speed is as
145 fast as possible: the image is decompressed (in 4:2:0 format) at a
146 quarter of its original size; then the image is enlarged again by pixel
147 doubling.
148
151 /etc/system.fiascorc
152 The systemwide initialization file.
153 $HOME/.fiascorc
156 The personal initialization file.
157
162 FIASCO_IMAGES
163 Save path for image files. Default is "./".
164 FIASCO_DATA
167 Search path for FIASCO files. Default is "./".
