For a MarkerTextBackground, this is the union of the bounding box of the Marker and the Text.

Product Availability

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

                 AutomationException

Draws the text background.

Description

The Draw method is used in a similar way to the ISymbol::Draw method. Note that ISymbol::Draw called on a TextSymbol coclass will also call ITextBackground::Draw, if a Background is set, thus drawing both the background and the text. Note that there is no Geometry required in this method; the location and size of the TextBackground is determined by the TextSymbol.
