    PCCViewer. MarkupLayerCollection

    (protected) new MarkupLayerCollection(viewerControl)

    The MarkupLayerCollection object is used to hold and manage the markup layers as they are added, removed, shown and hidden. These actions will determine what marks and comments are displayed.

    After creating a MarkupLayerCollection, PCCViewer.MarkupLayer objects may be added and removed from it. Additionally, mark references may also be added to it.

    The MarkupLayerCollection object also provides an event subscription method, to get notified of other types of information. See PCCViewer.MarkupLayerCollection.EventType.

    Parameters:

    Name Type Description
    viewerControl string

    The PCCViewer.ViewerControl for the loaded document.

    Example

    // Get the `MarkupLayerCollection` associated with the viewerControl
    var layerCollection = viewerControl.getMarkupLayerCollection()
    // Get all the layers in a collection
    var layers = layerCollection.getAll();
    // Remove a layer from a collection
    layerCollection.remove(layers[0].getId());
    
    //register some events
    layerCollection
      .on(PCCViewer.MarkupLayerCollection.EventType.MarkupLayerAdded,
          function(ev) {
              alert("Markup layer added to the collection with id = " + ev.layerId);
          })
      .on(PCCViewer.MarkupLayerCollection.EventType.MarkupLayerRemoved,
          function(ev) {
              alert("Markup layer removed from the collection with id = " + ev.layerId);
          });
