    Example
    Update the RGB colorizer on a raster layer
    await QueuedTask.Run(() =>
    {
      // Get the colorizer from the raster layer.
      CIMRasterColorizer rColorizer = rasterLayer.GetColorizer();
      // Check if the colorizer is an RGB colorizer.
      if (rColorizer is CIMRasterRGBColorizer rasterRGBColorizer)
      {
        // Update RGB colorizer properties.
        rasterRGBColorizer.StretchType = RasterStretchType.ESRI;
        // Update the raster layer with the changed colorizer.
        rasterLayer.SetColorizer(rasterRGBColorizer);
      }
    });
    Update the RGB colorizer on a mosaic layer
    await QueuedTask.Run(() =>
    {
      // Get the image sub-layer from the mosaic layer.
      ImageMosaicSubLayer mosaicImageSubLayer = mosaicLayer.GetImageLayer();
      // Get the colorizer from the image sub-layer.
      CIMRasterColorizer rColorizer = mosaicImageSubLayer.GetColorizer();
      // Check if the colorizer is an RGB colorizer.
      if (rColorizer is CIMRasterRGBColorizer rasterRGBColorizer)
      {
        // Update RGB colorizer properties.
        rasterRGBColorizer.StretchType = RasterStretchType.ESRI;
        // Update the image sub-layer with the changed colorizer.
        mosaicImageSubLayer.SetColorizer(rasterRGBColorizer);
      }
    });
    Update the RGB colorizer on an image service layer
    await QueuedTask.Run(() =>
    {
      // Get the colorizer from the image service layer.
      CIMRasterColorizer rColorizer = isLayer.GetColorizer();
      // Check if the colorizer is an RGB colorizer.
      if (rColorizer is CIMRasterRGBColorizer rasterRGBColorizer)
      {
        // Update RGB colorizer properties.
        rasterRGBColorizer.StretchType = RasterStretchType.ESRI;
        // Update the image service layer with the changed colorizer.
        isLayer.SetColorizer((CIMRasterColorizer)rasterRGBColorizer);
      }
    });
