Class: QgsPointCloudExtentRenderer

class qgis.core.QgsPointCloudExtentRenderer

Bases: QgsPointCloudRenderer

A renderer for 2d visualisation of point clouds which shows the dataset’s extents using a fill symbol.

New in version 3.18.

QgsPointCloudExtentRenderer(symbol: QgsFillSymbol = None) Constructor for QgsPointCloudExtentRenderer.

Optionally the symbol to use for showing the extent can be specified. If specified, ownership is transferred to the renderer. If no symbol is specified a default one will be created instead.

Methods

clone	rtype QgsPointCloudRenderer
create	Creates an extent renderer from an XML element.
createLegendNodes	param nodeLayer
defaultFillSymbol	Returns a new instance of the default fill symbol to use for showing point cloud extents.
fillSymbol	Returns the symbol used to render the cloud's extent.
renderBlock	param block
renderExtent	Renders a polygon extent geometry to the specified render context.
save	param doc
setFillSymbol	Sets the symbol used to render the cloud's extent.
startRender	param context
stopRender	param context
type	rtype str
