PCCViewer. MarkupLayer

(protected) new MarkupLayer(viewerControl, markReferencesopt)

The MarkupLayer object is used to group together marks and their associated comments. A layer may be persisted to the web tier using PCCViewer.ViewerControl#saveMarkupLayer. Also, a layer may be stored in a PCCViewer.MarkupLayerCollection where it can be retrieved for later use.

When creating a layer, mark references may be added. A mark reference is a JSON object that represents a comment that refers to a mark on another layer. When the current user comments on a mark that does not exist in his layer, then his persisted layer record will contain a reference to the mark while the full mark will exist in another record. Because records might be loaded out of order or in an incomplete set, this parameter provides a way to store the mark reference. If the record containing the full mark loads later then the data stored here can be attached to it.

After creating a layer, marks may be added and removed from it.

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

Parameters:
Name Type Attributes Description
viewerControl string

The PCCViewer.ViewerControl for the loaded document.

markReferences Object | Array.<Object> <optional>

The JSON reference node (or an array of them) from the markup layer record.

Example
// Optionally, specify any references to marks on another layer or layers
var markReference = {
     creationDateTime: "2015-06-12T21:20:58.527Z",
     data: {
         "key1": "value1",
         "key2": "value2"
     },
     markUid: "ZZZrOV8yMDE1LTA2LTExVDE5OjU5OjEwLjE3MlpfNDg2dzI5",
     text: "user 1 comment on user 3 mark"
};

// Create a new layer
var layer = new PCCViewer.MarkupLayer(viewerControl, markReference);

//register some events

    })
    .on(PCCViewer.MarkupLayer.EventType.MarkupLayerInteractionModeChanged, function(ev) {
        alert("Layer's interaction mode changed to: " + ev.interactionMode);
    })
    .on(PCCViewer.MarkupLayer.EventType.MarkupLayerHidden, function(ev) {
        alert("MarkupLayer#hide() called.");
    })
    .on(PCCViewer.MarkupLayer.EventType.MarkupLayerShown, function(ev) {
        alert("MarkupLayer#show() called.");
    });

// Create a new mark
var mark = viewerControl.addMark(1, "HighlightAnnotation");
// Add the mark to the layer
layer.addMarks(mark);
// Determine if a mark is contained in a layer
var markInLayer = layer.hasMark(mark.getId());
