[QGIS-Developer] Exporting point symbols from processing algorithm

[C Hamilton]

Nyall,

As usual thank you so much for your answers. I have one further question
with this. You said I need to set SqgMapSettings with the map scale and
extent. I probably want the map scale and extent from the canvas, but in a
processing algorithm I don't know how to get that information.

Thanks,

Calvin

As far as creating a render context goes -- the easiest way is via
> QgsRenderContext.fromMapSettings(). You create a QgsMapSettings
> object, set it all up with the desired map scale and extent, etc, and
> then convert it to a render context. This ensures that regardless of
> the size units used by the symbol (e.g. if it's in map units) it will
> be correctly sized...
