Member Function Documentation

`[override virtual noexcept]` Colormap::~Colormap()

Destructor.

`[static]` Esri::ArcGISRuntime::Colormap Colormap::create(const QList<QColor> &colors*, QObject **parent* = nullptr)

Returns a colormap with specified colors. Raster value of 0 gets mapped to the first color in the array, and each consecutive raster value maps to the subsequent color in the array.

colors - An array of colors.
parent - The optional parent QObject.

`[static, since Esri::ArcGISRuntime 300.0]` Esri::ArcGISRuntime::Colormap Colormap::create(const QMap<int, QColor> &colorMappings*, QObject **parent* = nullptr)

Returns a colormap with the specified mapping of raster values to colors.

colorMappings - A QMap of values with corresponding colors.
parent - The optional parent QObject.

This function was introduced in Esri::ArcGISRuntime 300.0.
