Class: QgsMarkerLineSymbolLayer

class qgis.core.QgsMarkerLineSymbolLayer(rotateMarker: bool = DEFAULT_MARKERLINE_ROTATE, interval: float = DEFAULT_MARKERLINE_INTERVAL)

Bases: qgis._core.QgsTemplatedLineSymbolLayerBase

Constructor for QgsMarkerLineSymbolLayer. Creates a marker line with a default marker symbol, placed at the specified interval (in millimeters).

The rotateMarker argument specifies whether individual marker symbols should be rotated to match the line segment alignment.

Line symbol layer type which draws repeating marker symbols along a line feature.
