    Example
    Update the raster colorizer on a raster layer
    await QueuedTask.Run(() =>
    {
      // Get the colorizer from the raster layer.
      CIMRasterColorizer rasterColorizer = rasterLayer.GetColorizer();
      // Update raster colorizer properties.
      rasterColorizer.Brightness = 10;
      rasterColorizer.Contrast = -5;
      rasterColorizer.ResamplingType = RasterResamplingType.NearestNeighbor;
      // Update the raster layer with the changed colorizer.
      rasterLayer.SetColorizer(rasterColorizer);
    });
    Update the raster 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 rasterColorizer = mosaicImageSubLayer.GetColorizer();
      // Update raster colorizer properties.
      rasterColorizer.Brightness = 10;
      rasterColorizer.Contrast = -5;
      rasterColorizer.ResamplingType = RasterResamplingType.NearestNeighbor;
      // Update the image sub-layer with the changed colorizer.
      mosaicImageSubLayer.SetColorizer(rasterColorizer);
    });
    Update the raster colorizer on an image service layer
    await QueuedTask.Run(() =>
    {
      // Get the colorizer from the image service layer.
      CIMRasterColorizer rasterColorizer = isLayer.GetColorizer();
      // Update the colorizer properties.
      rasterColorizer.Brightness = 10;
      rasterColorizer.Contrast = -5;
      rasterColorizer.ResamplingType = RasterResamplingType.NearestNeighbor;
      // Update the image service layer with the changed colorizer.
      isLayer.SetColorizer(rasterColorizer);
    });
