Layer.BlendMode Property
Gets or sets the blend mode that determines how the layer is combined with previously rendered layers.
Syntax
public LayerBlendMode BlendMode { get; set; }Property Value
Default: Differs depending on type. See the table below.
The blend mode used to combine the layer with previously rendered layers.
Default values
Remarks
A layer with a blend mode different from Normal will draw all of its features into a new image, which will finally be blended into the previously rendered layers.
In 3D, only the blend mode 'Normal' is supported.
Layers under a TileLayer with cacheAsBitmaps = 'True' will not cache the background color of the view.
 |
When a LayerBlendMode is used with an OpenGL drawable, OpenGL version 3.0 or later is required to use any other blend mode other than 'Normal'. If the OpenGL version is lower than 3.0, typically when running an application over a Remote Desktop connection, the blend mode will be treated as 'Normal'. These limitations do not apply to the DirectX renderer.
Example
// Set the layer blend mode to multiply
public static void SetLayerBlendMode(Layer layer)
{
// Set multiply blend mode
layer.BlendMode = LayerBlendMode.Multiply;
// Adjust how much this layer should contribute to the blend
layer.Opacity = 0.5;
}
