16 fiascotopnm - Convert compressed FIASCO image to PGM, or PPM
17 !!SYNOPSIS
18
19
20 __fiascotopnm__ [[''option'']...
21 [[''filename'']...
22 !!DESCRIPTION
23
24
25 __fiascotopnm__ decompresses the named FIASCO files, or
26 the Standard Input if no file is named, and writes the
27 images as PGM, or PPM files, depending on whether the FIASCO
28 im- age is black and white or color.
29 !!OPTIONS
30
31
32 All option names may be abbreviated; for example, --output
33 may be written --outp or --ou. For all options an one let-
34 ter short option is provided. Mandatory or optional argu-
35 ments to long options are mandatory or optional for short
36 options, too. Both short and long options are case sensi-
37 tive.
38
39
40 __-o__[[''name''],
41 __--output=__[[''name'']
42
43
44 Write decompressed image to the file ''name''.ppm (if
45 PPM) or ''name''.pgm (if PGM). If ''name''=- then
46 produce the image file on the standard output. The optional
47 argument ''name'' can be omitted, then the input file-
48 name is used as basename with the suffix .ppm or .pgm. In
49 case of video streams, the frames are stored in the files
50 ''name''.__N__.ppm where __N__ is the frame number
51 (of the form 00..0 - 99..9); output on the standard output
52 is not possible with video streams.
53
54
55 If ''name'' is a relative path and the environment
56 variable __FIASCO_IMAGES__ is a (colon-separated) list of
57 directories, then the output file(s) are written to the
58 first (writable) directory of this list. Otherwise, the
59 current directory is used to store the output
60 file(s).
61
62
63 __-z__, __--fast__
64
65
66 Decompress images in the 4:2:0 format; i.e., each chroma
67 channel is decompressed to an image of halved width and
68 height. Use this option on slow machines when the desired
69 frame rate is not achieved; the output quality is only
70 slightly de- creased.
71
72
73 __-d__, __--double__
74
75
76 Double the size of the X11 window both in width and height;
77 no pixel interpolation is used, each pixel is just replaced
78 by four identical pixels.
79
80
81 __-p__, __--panel__
82
83
84 Show a panel with play, stop, pause, record and ex- it
85 buttons to control the display of videos. When pressing the
86 record button, all frames are decom- pressed and stored in
87 memory. The other buttons work in the usual
88 way.
89
90
91 __-m__ ''N'', __--magnify=__''N''
92
93
94 Set magnification of the decompressed image. Posi- tive
95 values enlarge and negative values reduce the image width
96 and height by a factor of 2^|''N''|.
97
98
99 __-s__ ''N'', __--smooth=__''N''
100
101
102 Smooth decompressed image(s) along the partitioning borders
103 by the given amount ''N''. ''N'' is 1 (minimum) to 100
104 (maximum); default is 70. When ''N''=0, then the
105 smoothing amount specified in the FIASCO file is used
106 (defined by the FIASCO coder).
107
108
109 __-F__ ''N'', __--fps=__''N''
110
111
112 Set number of frames per second to ''N''. When using this
113 option, the frame rate specified in the FIASCO file is
114 overridden.
115
116
117 __-v__, __--version__
118
119
120 Print __fiascotopnm__ version number, then
121 exit.
122
123
124 __-f__ ''name'',
125 __--config=__''name''
126
127
128 Load parameter file ''name'' to initialize the options of
129 __fiascotopnm__. See file __system.fiascorc__ for an
130 example of the syntax. Options of __fiascotopnm__ are set
131 by any of the following methods (in the speci- fied
132 order):
