Class: QgsSimpleMarkerSymbolLayerBase¶

class qgis.core.QgsSimpleMarkerSymbolLayerBase(shape: QgsSimpleMarkerSymbolLayerBase.Shape = QgsSimpleMarkerSymbolLayerBase.Circle, size: float = DEFAULT_SIMPLEMARKER_SIZE, angle: float = DEFAULT_SIMPLEMARKER_ANGLE, scaleMethod: QgsSymbol.ScaleMethod = DEFAULT_SCALE_METHOD)¶

Bases: qgis._core.QgsMarkerSymbolLayer

Constructor for QgsSimpleMarkerSymbolLayerBase.

Parameters

shape – symbol shape for markers
size – symbol size (in mm)
angle – symbol rotation angle
scaleMethod – scaling method for data defined scaling

QgsSimpleMarkerSymbolLayerBase(QgsSimpleMarkerSymbolLayerBase)

Abstract base class for simple marker symbol layers. Handles creation of the symbol shapes but leaves the actual drawing of the symbols to subclasses.

New in version 2.16: Enums

Methods

`availableShapes`	Returns a list of all available shape types.
`bounds`
`decodeShape`	Attempts to decode a string representation of a shape name to the corresponding shape.
`encodeShape`	Encodes a shape to its string representation.
`renderPoint`
`setShape`	Sets the rendered marker shape.
`shape`	Returns the shape for the rendered marker symbol.
`shapeIsFilled`	Returns `True` if a symbol shape has a fill.
`startRender`
`stopRender`

availableShapes() → object¶: Returns a list of all available shape types.

bounds(self, point: Union[QPointF, QPoint], context: QgsSymbolRenderContext) → QRectF¶

decodeShape(name: str) → Tuple[QgsSimpleMarkerSymbolLayerBase.Shape, bool]¶

Attempts to decode a string representation of a shape name to the corresponding shape.

Parameters

name – encoded shape name
ok – if specified, will be set to True if shape was successfully decoded

Returns

decoded name
