Notes: You should call this BEFORE calling PetscDrawClear() and creating your image.

Requires that PETSc be configured with the option --with-afterimage to save the images and ffmpeg must be in your path to make the movie

If X windows generates an error message about X_CreateWindow() failing then Afterimage was installed without X windows. Reinstall Afterimage using the ./configure flags --x-includes=/pathtoXincludes --x-libraries=/pathtoXlibraries For example under Mac OS X Mountain Lion --x-includes=/opt/X11/include -x-libraries=/opt/X11/lib
