|
|
:py:class:`QgsInvertedPolygonRenderer` is a polygon-only feature renderer used to
|
|
display features inverted, where the exterior is turned to an interior
|
|
and where the exterior theoretically spans the entire plane, allowing
|
|
to mask the surroundings of some features.
|
|
|
|
It is designed on top of another feature renderer, which is called "embedded"
|
|
Most of the methods are then only proxies to the embedded renderer.
|
|
|
|
Features are collected to form one "inverted" polygon
|
|
during :py:func:`~renderFeature` and rendered on :py:func:`~stopRender`.

Constructor

|
|
%Docstring
|
|
|
|
:param enabled: enables or disables the preprocessing.
|
|
When enabled, geometries will be merged with an union before being rendered.
|
|
It allows fixing some rendering artifacts (when rendering overlapping polygons for instance).
|
|
This will involve some CPU-demanding computations and is thus disabled by default.

Creates a QgsInvertedPolygonRenderer by a conversion from an existing renderer.

:return: a new renderer if the conversion was possible, otherwise ``None``.
