Syntax

Visual Basic (Declaration)

public class CalloutMarkerSymbol : LabelSymbol

Example

This example creates a new CalloutMarkerSymbol with a beige background and partial transparency, and with a longer than default leader from the point labeled. It substitutes the existing label renderer with a new one containing the new CalloutMarkerSymbol. This layer, like most labeled layers, uses a GroupRenderer since it has a symbol renderer in addition to a label renderer.

' Create a new CalloutMarkerSymbol and set its properties

Dim calloutMarker As New CalloutMarkerSymbol()

calloutMarker.Font = New FontInfo("Arial", 14, Drawing.Color.Navy, FontStyle.Regular)

calloutMarker.Antialiasing = True

calloutMarker.BackColor = Drawing.Color.Beige

calloutMarker.BoundaryColor = Drawing.Color.Beige

calloutMarker.LeaderLength = 20

calloutMarker.Transparency = 30



' Retrieve an existing layer

Dim layer As FeatureLayer = mapView.Layers.FindByName("Cities")



' Create new label renderer

Dim labelRend As New SimpleLabelRenderer("NAME")

labelRend.Symbol = calloutMarker



' Replace the existing label renderer with the new one

' -- Layer has a symbol renderer as well as a label renderer, in a GroupRenderer

Dim groupRend As GroupRenderer = layer.Renderer

groupRend.Renderers.RemoveAt(1) ' label renderer is second renderer

groupRend.Renderers.Add(labelRend)

Remarks

This label symbol displays the text for point with callout boxes, which are boxes with a leader line pointing to the feature labeled.

CalloutMarkerSymbol works only with point layers.

CalloutMarkerSymbol is not valid for use in an acetate layer.

CalloutMarkerSymbol is not valid with ArcMap Server image services.
