plot3getframe — extract one frame from a UNIX plot file
plot3getframe
extracts a single frame from a multi-frame UNIX plot file.
Frames are separated by UNIX plot "erase" commands.
Specifying the
-v
(verbose) flag causes the number of each frame being skipped to
be printed on stderr.
Note that BRL 3-D UNIX plot is a superset of the standard UNIX plot format, thus this program can process normal plot files as well.
