[Plplot-general] Animation with plplot

[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

Hello 
 
I wish to use plplot to make simple physics animation (such as a mobile thrown 
in the air) on a Debian Sarge. 
The plplot version is 5.7.2, used with Fortran program. I can use C if 
necessary. 
 
I need a set of images which will be used to feed ffmpeg. 
 
Currently I use the postscript driver (1) : a call to plenv() for each frame 
put a new page in the 
file. Then pstoimg gives me the set of images. 
 
I guess it is not the best way. I tried to use the pbm driver. I got a big 
file, in which I guess the successive images are dumped. 
But I don't know how to extract them. 
 
I tried to use the plmeta driver to extract this files, unsuccessful. 
 
I tried to use the plmeta driver in conjunction with the -fam options or 
procedures, but I got unusable files or segmentations faults. 
 
Does somebody has a hint, or a program sample to lighten me ?? 


(1) Is there a way to drive the postscript driver to produce correctly 
oriented graphs : mine are counterclockwise rotated.
 
Sincerely yours
