示例1: testSizeUnit
# 需要导入模块: from qgis.core import QgsMarkerSymbol [as 别名]
# 或者: from qgis.core.QgsMarkerSymbol import setSizeUnit [as 别名]
def testSizeUnit(self):
# test sizeUnit and setSizeUnit
# create a marker symbol with a single layer
markerSymbol = QgsMarkerSymbol()
markerSymbol.deleteSymbolLayer(0)
markerSymbol.appendSymbolLayer(
QgsSimpleMarkerSymbolLayer(QgsSimpleMarkerSymbolLayerBase.Star, color=QColor(255, 0, 0),
strokeColor=QColor(0, 255, 0), size=10))
self.assertEqual(markerSymbol.sizeUnit(), QgsUnitTypes.RenderMillimeters)
markerSymbol.setSizeUnit(QgsUnitTypes.RenderMapUnits)
self.assertEqual(markerSymbol.sizeUnit(), QgsUnitTypes.RenderMapUnits)
self.assertEqual(markerSymbol.symbolLayer(0).sizeUnit(), QgsUnitTypes.RenderMapUnits)
# add additional layers
markerSymbol.appendSymbolLayer(
QgsSimpleMarkerSymbolLayer(QgsSimpleMarkerSymbolLayerBase.Star, color=QColor(255, 0, 0),
strokeColor=QColor(0, 255, 0), size=10))
markerSymbol.appendSymbolLayer(
QgsSimpleMarkerSymbolLayer(QgsSimpleMarkerSymbolLayerBase.Star, color=QColor(255, 0, 0),

# should now be mixed size units
self.assertEqual(markerSymbol.sizeUnit(), QgsUnitTypes.RenderUnknownUnit)
markerSymbol.setSizeUnit(QgsUnitTypes.RenderPixels)
self.assertEqual(markerSymbol.sizeUnit(), QgsUnitTypes.RenderPixels)
# all layers should have size unit set
self.assertEqual(markerSymbol.symbolLayer(0).sizeUnit(), QgsUnitTypes.RenderPixels)
self.assertEqual(markerSymbol.symbolLayer(1).sizeUnit(), QgsUnitTypes.RenderPixels)
self.assertEqual(markerSymbol.symbolLayer(2).sizeUnit(), QgsUnitTypes.RenderPixels)
