BlendRenderer::BlendRenderer(Esri::ArcGISRuntime::Raster *elevationRaster, const QList<double> &outputMinValues, const QList<double> &outputMaxValues, const QList<double> &sourceMinValues, const QList<double> &sourceMaxValues, const QList<double> &noDataValues, const QList<double> &gammas, Esri::ArcGISRuntime::ColorRamp *colorRamp, double altitude, double azimuth, double zFactor, Esri::ArcGISRuntime::SlopeType slopeType, double pixelSizeFactor, double pixelSizePower, int outputBitDepth, QObject *parent = nullptr)

Constructor that takes the following parameters:

• elevationRaster - The raster elevation source.
• outputMinValues - The minimum output values for blending, one for each band.
• outputMaxValues - The maximum output values for blending, one for each band.
• sourceMinValues - The minimum input values for blending, one for each band.
• sourceMaxValues - The maximum input values for blending, one for each band.
• noDataValues - The no-data values, one for each band.
• gammas - The gamma adjustments.
• colorRamp - The color ramp object for creating the blend renderer.
• altitude - The light's angle of elevation above the horizon.
• azimuth - The light's relative angle along the horizon measured clockwise, where 0 is north.
• zFactor - The z-factor used to convert z unit to x,y units.
• slopeType - The SlopeType.
• pixelSizeFactor - The pixel size factor to account altitude changes as the viewer zooms.
• pixelSizePower - The pixel size power to account altitude changes as the viewer zooms.
• outputBitDepth - The output bit depth.
• parent - The optional parent.
