class qgis.core.QgsProcessingParameterCoordinateOperation(name: str, description: str = '', defaultValue: Any = None, sourceCrsParameterName: str = '', destinationCrsParameterName: str = '', staticSourceCrs: Any = None, staticDestinationCrs: Any = None, optional: bool = False)

Bases: QgsProcessingParameterDefinition

Constructor for QgsProcessingParameterCoordinateOperation.

QgsProcessingParameterCoordinateOperation(QgsProcessingParameterCoordinateOperation)

A coordinate operation parameter for processing algorithms, for selection between available coordinate operations to use when projecting between a source and destination coordinate reference system.

QgsProcessingParameterCoordinateOperation should be evaluated by calling QgsProcessingAlgorithm.parameterAsString()

New in version 3.12.
