AGSSimpleLineSymbol Class Reference

---

Description

Instances of this class represent simple line symbols. Symbols describe how graphics look on the map. Different symbols are used for graphics with different geometry types. Line symbols are used to display those graphics which are based on a polyline geometry. Simple line symbols display graphics using predefined line style patterns such as solid, dash, dot, etc.
