AGSPictureFillSymbol Class Reference

---

Description

Instances of this class represent picture fill symbols. Symbols describe how graphics look on the map. Different symbols are used for graphics with different geometry types. Fill symbols are used to display those graphics which are based on a polygon geometry. The symbol can fill the interior of a polygon graphic by repeating a given picture. In addition, the symbol can have an optional outline which is defined by a line symbol.

Defined in:

AGSPictureFillSymbol.h ( ArcGIS library)
