 **PDF**, ...

 **Note:** It is important to note that any figures containing WebGL traces (i.e. of type `scattergl`, `heatmapgl`, `contourgl`, `scatter3d`, `surface`, `mesh3d`, `scatterpolargl`, `cone`, `streamtube`, `splom`, or `parcoords`) that are exported in a vector format will include encapsulated rasters, instead of vectors, for some parts of the image.

 If `kaleido` is installed, it will automatically be used to perform image export.  If it is not installed, plotly.py will attempt to use `orca` instead. The `engine` argument to the `to_image` and `write_image` functions can be used to override this default behavior.
 
 Here is an example of specifying that orca should be used:
-```python
+~~~python
 fig.to_image(format="png", engine="orca")
-```
+~~~
 
 And, here is an example of specifying that Kaleido should be used:
-```python
+~~~python
 fig.to_image(format="png", engine="kaleido")
