ILineCallout Interface

Provides access to members that control the line callout.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


LineCallouts provide a filled background for text that can be linked, by a line, to an anchor point at a specified tolerance. The symbols used for the LeaderLine, Border and AccentBar can be changed to suit the needs of the specific application. Use the Style property to select from several different shapes and positioning of the LeaderLine. Use the ICallout and the ITextMargins interfaces to set additional properties for ILineCallouts.

Classes that implement ILineCallout

Classes Description
LineCallout A series of line symbols that link text to a specified location.


The LeaderLine property sets the symbol used to draw the leader line and can be set to any LineSymbol object. Similarly you can change the appearance of the accent bar by setting the AccentBar property.

The spacing between the Border and the AccentBar can be adjusted by setting the Gap property. This property indicates the separation between the center of the AccentBar and the edge of the Border as a distance in points and does not account for think outlines on either the AccentBar or Border.
