Class: QgsMapRendererSequentialJob¶

class qgis.core.QgsMapRendererSequentialJob¶

Bases: qgis._core.QgsMapRendererQImageJob

Job implementation that renders everything sequentially in one thread.

The resulting map image can be retrieved with renderedImage() function. It is safe to call that function while rendering is active to see preview of the map.
