Synopsis

#include "petscdraw.h" 
PetscErrorCode  PetscDrawSetSaveFinalImage(PetscDraw draw,const char filename[])
Collective on PetscDraw

Input Parameter

draw - the graphics context
filename - name of the file, if NULL or empty uses name set with PetscDrawSetSave() or name of draw object

Options Database Command

-draw_save_final_image <filename> - filename could be name.ext or .ext (where .ext determines the type of graphics file to save, for example .png)

Notes

You should call this BEFORE creating your image and calling PetscDrawSave(). The supported image types are .png, .gif, and .ppm (PETSc chooses the default in that order). Support for .png images requires configure --with-libpng. Support for .gif images requires configure --with-giflib. Support for .jpg images requires configure --with-libjpeg. Support for .ppm images is built-in. The PPM format has no compression (640x480 pixels ~ 900 KiB).
