bool QgsDatumTransformStore::hasEntryForLayer ( QgsMapLayer * layer ) const

Definition at line 48 of file qgsdatumtransformstore.cpp.

◆ readXML()

void QgsDatumTransformStore::readXML ( const QDomNode & parentNode )

Definition at line 77 of file qgsdatumtransformstore.cpp.

◆ setDestinationCrs()

void QgsDatumTransformStore::setDestinationCrs ( const QgsCoordinateReferenceSystem & destCrs )

Definition at line 32 of file qgsdatumtransformstore.cpp.

◆ transformation()

const QgsCoordinateTransform * QgsDatumTransformStore::transformation ( QgsMapLayer * layer ) const

Will return transform from layer's CRS to current destination CRS.

Will emit datumTransformInfoRequested signal if the layer has no entry. Returns an instance from QgsCoordinateTransformCache
