Raster renderer that generates contours on the fly for a source raster band.

  public:
    explicit QgsRasterContourRenderer( QgsRasterInterface *input );
%Docstring
Creates a contour renderer
%End
    ~QgsRasterContourRenderer();


    virtual QgsRasterContourRenderer *clone() const /Factory/;

%Docstring
QgsRasterContourRenderer cannot be copied. Use :py:func:`~QgsRasterContourRenderer.clone` instead.
%End

    static QgsRasterRenderer *create( const QDomElement &elem, QgsRasterInterface *input ) /Factory/;
%Docstring
Creates an instance of the renderer based on definition from XML (used by renderer registry)

    int inputBand() const;
%Docstring
Returns the number of the input raster band
%End
    void setInputBand( int band );
%Docstring
Sets the number of the input raster band
%End

    double contourInterval() const;
%Docstring
Returns the interval of contour lines generation
%End
    void setContourInterval( double interval );
%Docstring
Sets the interval of contour lines generation
%End

    QgsLineSymbol *contourSymbol() const;
%Docstring
Returns the symbol used for contour lines
%End
    void setContourSymbol( QgsLineSymbol *symbol /Transfer/ );
%Docstring
Sets the symbol used for contour lines. Takes ownership of the passed symbol
%End

    double contourIndexInterval() const;
%Docstring
Returns the interval of index contour lines (index contour lines are typical further apart and with a wider line symbol)
%End
    void setContourIndexInterval( double interval );
%Docstring
Sets the interval of index contour lines (index contour lines are typical further apart and with a wider line symbol)
%End

    QgsLineSymbol *contourIndexSymbol() const;
%Docstring
Returns the symbol of index contour lines
%End
    void setContourIndexSymbol( QgsLineSymbol *symbol /Transfer/ );
%Docstring
Sets the symbol of index contour lines
%End

    double downscale() const;
%Docstring
Returns by how much the renderer will scale down the request to the data provider.
For example, for a raster block 1000x500 with downscale 10, the renderer will request raster 100x50 from provider.
Higher downscale makes contour lines more simplified (at the expense of losing some detail).
The value of one means there will be no downscaling.
%End

    void setDownscale( double scale );
%Docstring
Sets by how much the renderer will scale down the request to the data provider.
