### Synopsis

    PetscErrorCode  PetscDrawSetSave(PetscDraw draw,const char filename[])

Collective on PetscDraw

### Input Parameter

| draw | - the graphics context
| filename | - name of the file, if .ext then uses name of draw object plus .ext using .ext to determine the image type

### Options Database Command

| -draw_save <filename> | - filename could be name.ext or .ext (where .ext determines the type of graphics file to save, for example .png)
| -draw_save_final_image [optional filename] | - saves the final image displayed in a window

Notes: You should call this BEFORE creating your image and calling PetscDrawSave(). The supported image types are .png, .gif, .jpg, 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).
