Update the RGB colorizer on a raster layer

C#

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

C#

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

C#

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);
  }
});
