public class IlvS57DataSource extends IlvDefaultTilableDataSource
IlvS57DataSource
represents a data source to read S57 files.
Simplified rendering can be activated or deactivated by calling
setSimplifiedRendering(boolean )
.
Rendering Type | Description |
Activated | Whatever the object attributes are, S52 symbols are rendered using a predefined icon for each object type. Polygon and polyline colors are likewise predefined. |
Deactivated | Rogue Wave JViews Maps for Defense uses the IHO ECDIS Presentation library (Edition 3.3, March 2004) definitions to create S52 symbols according to attribute content. |
