class TransformPair(sourceTransformId: int = -1, destinationTransformId: int = -1)¶

Bases: sip.wrapper

Constructor for a TransformPair with the specified sourceTransformId and destinationTransformId transforms.

QgsDatumTransform.TransformPair(QgsDatumTransform.TransformPair)

Parameters

sourceTransformId (int = -1) –
destinationTransformId (int = -1) –

sourceTransformId¶

datumTransformInfo(datumTransformId: int) → QgsDatumTransform.TransformInfo¶

Returns detailed information about the specified datumTransformId. If datumTransformId was not a valid transform ID, a TransformInfo with TransformInfo.datumTransformId of -1 will be returned.
