__init__(symbol: QgsFillSymbol | None = 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.

Parameters:

symbol (Optional[QgsFillSymbol] = None)

static create(element: QDomElement, context: QgsReadWriteContext) → QgsPointCloudRenderer | None[source]

Creates an extent renderer from an XML element.

Parameters:
Return type:

Optional[QgsPointCloudRenderer]

static defaultFillSymbol() → QgsFillSymbol | None[source]

Returns a new instance of the default fill symbol to use for showing point cloud extents.

Return type:

Optional[QgsFillSymbol]

fillSymbol(self) → QgsFillSymbol | None[source]

Returns the symbol used to render the cloud’s extent.
