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.

Class Hierarchy¶

Base classes¶

QgsProcessingParameterDefinition

Base class for the definition of processing parameters.

Methods

`destinationCrs`	Returns the static destination CRS, or an invalid value if this is not set.
`destinationCrsParameterName`	Returns the name of the destination CRS parameter, or an empty string if this is not set.
`setDestinationCrs`	Sets the static destination crs.
`setDestinationCrsParameterName`	Sets the name of the destination CRS parameter.
`setSourceCrs`	Sets the static source crs.
`setSourceCrsParameterName`	Sets the name of the source CRS parameter.
`sourceCrs`	Returns the static source CRS, or an invalid value if this is not set.
`sourceCrsParameterName`	Returns the name of the source CRS parameter, or an empty string if this is not set.

Static Methods

`fromScriptCode`	Creates a new parameter using the definition from a script code.
`typeName`	Returns the type name for the parameter class.
