[explicit] BlendRenderer::BlendRenderer(Esri::ArcGISRuntime::Raster *elevationRaster, QObject *parent = nullptr)

Constructor that takes an elevationRaster with an optional parent.

The default values are:

• minValues - none
• maxValues - none
• gammas - none
• altitude - 45 degrees
• azimuth - 315 degrees
• zFactor - 1
• slopeType - SlopeType::None
• pixelSizeFactor - 1
• pixelSizePower - 1
• outputBitDepth - 8

BlendRenderer::BlendRenderer(Esri::ArcGISRuntime::Raster *elevationRaster, double altitude, double azimuth, double zFactor, QObject *parent = nullptr)

Constructor that takes the following parameters:

• elevationRaster - The raster elevation source.
• 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.
• parent - The optional parent.

The default values are:

• minValues - none
• maxValues - none
• gammas - none
• slopeType - SlopeType::None
• pixelSizeFactor - 1
• pixelSizePower - 1
• outputBitDepth - 8

• sourceMaxValues - QList of double. Input stretch values, one for each band. Can be empty.
• noDataValues - QList of double. NoData values, one for each band. Can be empty.
• gammas - QList of double. Gamma adjustment. Can be empty.
• colorRamp - The color ramp object.
• altitude - Altitude angle of the light source.
• azimuth - Azimuth angle of the light source, measured clockwise from north.
• zFactor - Factor to convert z unit to x,y unit, default is 1.
• slopeType - SlopeType.
• pixelSizeFactor - Pixel size factor, default is 1.
• pixelSizePower - Pixel size power value, default is 1.
• outputBitDepth - Output bit depth, default is 8-bit.
• parent - The optional parent QObject.
