    Public Functions

    ColormapRenderer(const QList<QColor> &colors, QObject *parent = nullptr)
    ColormapRenderer(Esri::ArcGISRuntime::Colormap *colormap, QObject *parent = nullptr)
    virtual ~ColormapRenderer() override
    Esri::ArcGISRuntime::Colormap *colormap() const
    QList<QColor> colors() const

    Detailed Description

    All cells matching the specified value will be rendered using the mapped color. This is useful for thematic mapping tasks such as land classification when you want the values in the raster layer to be represented by a specified color. This concept of this class is similar to a UniqueValueRenderer, except that ColormapRenderer is specifically for rendering raster cell values.

    [explicit] ColormapRenderer::ColormapRenderer(const QList<QColor> &colors, QObject *parent = nullptr)

    Creates a raster colormap renderer.

    [explicit] ColormapRenderer::ColormapRenderer(Esri::ArcGISRuntime::Colormap *colormap, QObject *parent = nullptr)
