Topomovie is a csh script which automates the
processes of converting, cropping, and combining the image files which
result from running the tbat(?) script. Topomovie will combine the .ps.gz
files in each directory specified on the command line (or .ppm files, if
the -p option is used) into a single MPEG movie or animated GIF.
process unzips each file, then uses ghostscript to convert the resulting
.ps file into a .ppm file (see ppm(5)
for more info). The vital region of
the .ppm file is then removed and saved, scaled (if the -s option is used),
and then added to the frame of the movie being constructed at that time.
Directory names and options may appear in any order on the command
line. All options have a "long" and a "short" version, which are equivalent.
These options are available for topomovie:
Topomovie is mostly new code, but is in
concept based on rgb2mpg by Marty Sereno. The .ps->.ppm conversion is based
on a line in pstopnm by Alberto Accomazzi. Tbat(?) was written by Tim Rohrer,
who also aided in the development of this script.
- -a, --animatedgif
- Output an animated
GIF rather than an MPEG. The default is to create an MPEG movie.
- -b, --both
- Output both an animated GIF and an MPEG movie.
- -c, --cols num
- Arrange the frame
such that the files in num directories appear in each column of the output
movie. The result of multiplying the values given for the -c and -r options
much equal the number of directories listed on the command line. Default
- -d, --delay num
- Set the delay between frames of an animated GIF to num
1/100ths of a second. The default is 10, which equals 1 frame per 1/10th
of a second, and also equals 10 frames per second. This option only applies
when the output is an animated GIF.
- -g, --keepgif
- Create GIF files for each
individual frame (irregardless of whether or not the output will be an
animated GIF) and keep them after the program exits. These files will be
stored in the temporary directory below the current directory.
- -h, --help
- -k, --keepppm
- Keep the intermediary .ppm files after the program
exits. These files will be stored in the same directories given on the command
- -n, --nice
- Run at a higher niceness. This gives other running programs
priority to use system resources. Useful when running topomovie as a background
job. This option may appear on the command line multiple times. See renice(8)
for more info.
- -o, --optimize num
- Optimize the size of the output file. 0=least/none
1=more, 2=most. For MPEG output, smaller files mean lower quality. For GIF
output, smaller files may be less compatible with various GIF viewers. Default
- -p, --ppm
- Run the program using .ppm files as the input. This option is
used after topomovie has been run once using the -k option. Using saved .ppm
files increases speed, but can lead to problems if those .ppm files have
been altered or damaged.
- -r, --rows num
- Arrange the frame such that the files
in num directories appear in each row of the output movie. The result of
multiplying the values given for the -c and -r options much equal the number
of directories listed on the command line. Default is 1.
- -s, --scale num
the movie by num amount. Num is an integer or decimal number. Values larger
than 1 result in a larger movie, while values less than 1 result in a smaller
movie. If the -g or -k option is used with this option, the saved files will
also be shrunk by this amount. Default is 1.
- -t, --text
- Include the text appearing
at the top of each .ps file in the movie. The default is to exclude this
