%Docstring(signature="appended")
|
|
A polygon-only feature renderer used to display features inverted.
|
|
|
|
The exterior of the polygon 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`.

%Docstring
|
|
Returns ``True`` if the geometries are to be preprocessed (merged with
|
|
an union) before rendering.
|

.. seealso:: :py:func:`setPreprocessingEnabled`
|
|
%End

void setPreprocessingEnabled( bool enabled );
|
|
%Docstring
|
|
Sets whether geometries preprocessing is enabled.
|
|
|
|
When enabled, geometries will be merged with an union before being
|
|
rendered.
|
|
|
|
This 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.
|

``None``.
