    Syntax
    Example
    Create a new colorizer based on a default colorizer definition and apply it to the raster layer
    await QueuedTask.Run(async () =>
    {
      // Check if the Stretch colorizer can be applied to the raster layer.
      if (rasterLayer.GetApplicableColorizers().Contains(RasterColorizerType.StretchColorizer))
      {
        // Create a new Stretch Colorizer Definition using the default constructor.
        StretchColorizerDefinition stretchColorizerDef_default = new StretchColorizerDefinition();
        // Create a new Stretch colorizer using the colorizer definition created above.
        CIMRasterStretchColorizer newStretchColorizer_default =
    await rasterLayer.CreateColorizerAsync(stretchColorizerDef_default) as CIMRasterStretchColorizer;
        // Set the new colorizer on the raster layer.
        rasterLayer.SetColorizer(newStretchColorizer_default);
      }
    });
    Create a new colorizer based on a custom colorizer definition and apply it to the raster layer
    await QueuedTask.Run(async () =>
    {
      // Check if the Stretch colorizer can be applied to the raster layer.
      if (rasterLayer.GetApplicableColorizers().Contains(RasterColorizerType.StretchColorizer))
      {

        // for band index, stretch type, gamma and color ramp.

    Create a new colorizer based on a default colorizer definition and apply it to the mosaic layer
    await QueuedTask.Run(async () =>

      }
    });
    Create a new colorizer based on a custom colorizer definition and apply it to the mosaic layer
    await QueuedTask.Run(async () =>
    {
      // Get the image sub-layer from the mosaic layer.
      ImageMosaicSubLayer mosaicImageSubLayer = mosaicLayer.GetImageLayer();

        // Set the new colorizer on the image sub-layer.
        mosaicImageSubLayer.SetColorizer(newStretchColorizer_custom);
      }
    });
    Create a new colorizer based on a default colorizer definition and apply it to the image service layer
    await QueuedTask.Run(async () =>
    {
      // Check if the Stretch colorizer can be applied to the image service layer.
      if (isLayer.GetApplicableColorizers().Contains(RasterColorizerType.StretchColorizer))

      }
    });
    Calculate Raster statistics
    //If a raster dataset has statistics, you can create a raster layer and get these statistics by accessing the colorizer.
    await QueuedTask.Run(() =>
    {
      //Accessing the raster layer
      var lyr = MapView.Active.Map.GetLayersAsFlattenedList().OfType<BasicRasterLayer>().FirstOrDefault();

      var stats = colorizer.StretchStats;
      var max = stats.max;
      var min = stats.min;
