class QgsRasterProjector : QgsRasterInterface
{
%Docstring(signature="appended")
Implements approximate projection support for optimised raster
transformation.
:py:class:`QgsRasterProjector` calculates a grid of points in the source
CRS for a specific target CRS and extent. These are used to calculate
affine transformation matrices, which can be used instead of raw PROJ
transformations for optimised bulk reprojection of points.
