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.
