Class: QgsHashedLineSymbolLayer

class qgis.core.QgsHashedLineSymbolLayer(rotateSymbol: bool = True, interval: float = 3)

Bases: QgsTemplatedLineSymbolLayerBase

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

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

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

New in version 3.8.

Parameters
  • rotateSymbol (bool = True) –

  • interval

create(properties: Dict[str, str] = {}) → QgsSymbolLayer

Creates a new QgsHashedLineSymbolLayer, using the settings serialized in the properties map (corresponding to the output from QgsHashedLineSymbolLayer.properties() ).
