AddLayerConfiguration Method

The AddLayerConfiguration method is used to insert a new layer configuration to a document. This method takes 1 string parameter, the unique layer configuration ID.

In case the layer configuration ID is not unique the method will internally generate a unique ID and return it. This returned layer configuration ID (might be identical to input) should be used for all layer configuration operations.

 

Syntax

Visual Basic .NET:

Sub AddLayerConfiguration(ByRef configID As String)

C#:

void AddLayerConfiguration(ref string configID)

 

Parameters

configID

This is the unique ID for this layer configuration. It is important that this ID be saved by the caller.

 

Remarks

Before creating a LayerConfig object, we need to check if the document already has a layer config and use it, rather than adding a new one.  Otherwise, it could corrupt the final PDF file.

 

If developer wants to add layers to existent PDF file, it is mandatory to delete any existent layer using the method DeleteAllLayers before adding the new layers.

 

For the moment, it is not possible to modify or append layers to existent layers.

 

The Layer and LayerConfiguration Attributes contains the details information for configure the layers.
