  • class Esri::ArcGISRuntime::ColormapRenderer

    A ColormapRenderer provides a discrete mapping of raster pixel values to colors. More...

    Header: #include <ColormapRenderer>
    Since: Esri::ArcGISRuntime 100.0
    Inherits: Esri::ArcGISRuntime::RasterRenderer

    This class was introduced in Esri::ArcGISRuntime 100.0.

    Public Functions

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

    Detailed Description

    All pixels matching the specified value will be rendered using the mapped color. This is useful for thematic mapping tasks such as land classification. This concept of this class is similar to a UniqueValueRenderer, except that ColormapRenderer is specifically for rendering raster pixel values.
