getLayerOrderLayer

Get the layer associated with a layer display order node.
getLayerOrderLayer([in] LONG orderHandle, [out, retval] LONG *layerHandle)
PDF files with layers contain a tree structure that specifies the way layers are intended to be displayed to the user. Each node in the tree has either a name or a layer. Named nodes are used to provide a hierarchical structure for the layers, with labels to help the user. Each node also optionally has a list of child nodes.

This function returns the layer associated with the specified layer order tree node. It should only be called if getLayerOrderIsName returns false for the node.

VB6:
scanLayerOrder pdf.getLayerOrderRoot ... Sub scanLayerOrder(ByVal order As Long) Dim name As String Dim layer As Long If pdf.getLayerOrderIsName(order) Then ' this node has a name name = pdf.getLayerOrderName(order) ... Else ' this node has a layer layer = pdf.getLayerOrderLayer(order) ... End If nChildren = pdf.getLayerOrderNumChildren(order) For i = 0 To nChildren - 1 scanLayerOrder pdf.getLayerOrderChild(order, i) Next i End Sub
