Class: QgsLayoutSize

class qgis.core.QgsLayoutSize(width: float, height: float, units: QgsUnitTypes.LayoutUnit = QgsUnitTypes.LayoutMillimeters)

Bases: sip.wrapper

Constructor for QgsLayoutSize.

Parameters

• width – width

• height – height

• units – units for width and height

QgsLayoutSize(size: QSizeF, units: QgsUnitTypes.LayoutUnit = QgsUnitTypes.LayoutMillimeters) Constructor for QgsLayoutSize.

QgsLayoutSize(units: QgsUnitTypes.LayoutUnit = QgsUnitTypes.LayoutMillimeters) Constructor for an empty layout size

Parameters

units – units for measurement

QgsLayoutSize(QgsLayoutSize)

This class provides a method of storing sizes, consisting of a width and height, for use in QGIS layouts. Measurement units are stored alongside the size.

QgsLayoutMeasurementConverter

Note

This class does not inherit from QSizeF since QSizeF includes methods which should not apply to sizes with units. For instance, the + and - operators would mislead users of this class to believe that addition of two QgsLayoutSize with different unit types would automatically convert units. Instead, all unit conversion must be handled by a QgsLayoutMeasurementConverter so that conversion between paper and screen units can be correctly performed.
