# PetscDrawSetSave
Saves images produced in a `PetscDraw` into a file 
## Synopsis
```
#include "petscdraw.h" 
PetscErrorCode PetscDrawSetSave(PetscDraw draw, const char filename[])
```
Collective


## Input Parameters

- ***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 Keys

- ***-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
- ***-draw_save_single_file -*** saves each new image in the same file, normally each new image is saved in a new file with filename/filename_%d.ext





## Note
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).
