Use this interface to changes brightness, contrast, and transparency for a layer. The controls on the Effects toolbar in ArcMap utilize this interface. Not all layers support all layer effects. For example, FeatureLayer objects only support transparency, while RasterLayer objects support all effects. Before you attempt to change a layer effect, you should check to see if the layer supports the effect. Use
SupportsBrightnessChange, SupportsContrastChange, and SupportsTransparency for this.
The display settings on your computer must be set to True Color for layer effects to work correctly.
