This class represents a coordinate reference system (CRS).
A class to represent a 2D point.
Definition qgspointxy.h:60
A rectangle specified with double values.
QgsCoordinateReferenceSystem crs() const
Returns CRS of the tiling scheme.
QgsRectangle fullExtent() const
Returns the full extent used in the constructor, which might not be square.
QgsTilingScheme()=default
Creates invalid tiling scheme.
