Detailed Description
This renderer can be used for viewing color aerial photography, which is a three-band raster dataset, or to display different combinations of bands when working with multi-band raster datasets, such as satellite or aerial imagery.
Relevant samples:
- RGB renderer: Apply an RGB renderer to a raster layer to enhance feature visibility.

[override virtual] RGBRenderer::~RGBRenderer()
Destructor.
QList<int> RGBRenderer::bandIndexes () const
Returns the indexes of bands of a multi-band raster dataset that the renderer is based on.
The band specified by the 0th index is used as the Red band, 1st index as the Green band, and 2nd index as the Blue band.
Esri::ArcGISRuntime::Raster *RGBRenderer::panchromaticRaster () const
Returns the high-resolution panchromatic raster to use as a basis for panchoromatic sharpening.
Pan-sharpening uses a higher-resolution panchromatic image (or raster band) to fuse with a lower-resolution multi-band raster dataset. The result produces a multi-band raster dataset with the resolution of the panchromatic raster where the two rasters fully overlap.
Note: Please see the ArcGIS Desktop documentation for further details.
Esri::ArcGISRuntime::PansharpenType RGBRenderer::pansharpenType () const
Returns the type of panchromatic sharpening method that is applied.
QList<double> RGBRenderer::weights() const
Returns the weights to use in the panchromatic sharpening method.
Each of method uses different models to improve the spatial resolution while maintaining the color, and some are adjusted to include a weighting so that a fourth band can be included (such as the near-infrared band available in many multispectral image sources). By adding the weighting and enabling the infrared component, the visual quality in the output colors is improved.
