PetscDrawSetSaveFinalImage#

Saves the final image produced in a PetscDraw into a file

Synopsis#

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

Collective

Input Parameters#

  • draw - the graphics context

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

Options Database Key#

  • -draw_save_final_image - 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).
