Product Availability

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

Description

The TextBackground abstract class defines the common properties of the different types of background�MarkerTextBackground, BalloonCallout, and LineCallout. Use a MarkerTextBackground to draw text over a single glyph from a font (for example, a highway shield and number). A BalloonCallout draws a rectangular- or balloon-shaped background for a text string with a predefined leader line. A LineCallout is similar to a BalloonCallout but has a different leader line with a user-defined style and an accent bar.

Callout text backgrounds can be used for TextSymbol objects with a TextPath set, but note that the callout will produce a background to the envelope of the text, not one following the path.

Examples of the three types of text background: marker text background, balloon callout, and line callout.
