Class: QgsProcessingParameterCoordinateOperation

A coordinate operation parameter for processing algorithms.

This parameter allows 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().

Added in version 3.12.
