Feras,
You are in luck, we do have a mechanism that automatically save PETSc X
images as Gif files. I delayed responding so I could clean up the code for you
to use.
1) It is only in petsc-dev http://www.mcs.anl.gov/petsc/developers/index.html
2) you must first install afterimage (easy) which installs in /usr/local
3) ./configure PETSc with the additional option --with-afterimage
4) when running your program just use the extra command line option
-draw_save or use the function PetscDrawSetSave() on the draw object you
create before using it
5) If you want to generate a movie of all the images once the problem is
complete also install ffmpeg and also use the run time option -draw_save_movie
6) When generating your images make sure they are all open and fulling
displayed on the screen, afterimage will not function if the window is not
fully visible.
7) Report all problems to petsc-maint at mcs.anl.gov
8) Have fun
9) Like all PETSc graphics this is a useful tool for debugging and
algorithmic development etc, it is not intended to produce publication quality
graphics
