Detailed Description

Helper class for transform of coordinates (QgsPoint) to a different coordinate reference system.

It requires connection of transformation context from mapSettings, source position and source CRS to calculate projected position in desired destination CRS.

Note:

QML Type: CoordinateTransformer
