public interface ILayerEffects
extends Serializable

Provides access to members that control layer effects.

Remarks

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.

Returns:

The supported

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setSupportsInteractive

void setSupportsInteractive(boolean supported)
                            throws IOException,
                                   AutomationException

Indicates if the layer supports interactive effects changes.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

supported - The supported (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isSupportsInteractive

boolean isSupportsInteractive()
                              throws IOException,
                                     AutomationException

Indicates if the layer supports interactive effects changes.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The supported

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getTransparency

short getTransparency()

Remarks

When you set Transparency for a FeatureLayer, a TransparencyDisplayFilter is created and applied to the layer. You can accomplish the same effect by manually creating a new TransparencyDisplayFilter using IDisplayFilter, and then assigning it to a layer using IDisplayFilterManager.
