movie, draw_frame
or movie, draw_frame, time_limit
or movie, draw_frame, time_limit, min_interframe
runs a movie based on the given DRAW_FRAME function. The movie
stops after a total elapsed time of TIME_LIMIT seconds, which
defaults to 60 (one minute), or when the DRAW_FRAME function
returns zero.
func draw_frame(i)
{
// Input argument i is the frame number.
// draw_frame should return non-zero if there are more
// frames in this movie. A zero return will stop the
// movie.
// draw_frame must NOT include any fma command if the
// making_movie variable is set (movie sets this variable
// before calling draw_frame)
}
If MIN_INTERFRAME is specified, a pauses will be added as
necessary to slow down the movie. MIN_INTERFRAME is a time
in seconds (default 0).
The keyword bracket_time= (again a time in seconds) can be
used to adjust the duration of the pauses after the first
and last frames. It may also be a two element array [beg, end].
If the pause at the end is greater than five seconds, you will
be prompted to explain that hitting will abort the final
pause.
If every frame of your movie has the same limits, use the
limits command to fix the limits before you call movie.
BUG: If you hit to start a movie early, it will not
pause at the end of the movie at all. You probably should
not use long initial pauses.
