All Implemented Interfaces:

IlvPersistentObject, Serializable

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	Perforce JViews Maps for Defense uses the IHO ECDIS Presentation library (Edition 3.3, March 2004) definitions to create S52 symbols according to attribute content.

The following limitations apply to the use of the ECDIS Presentation library:

• Conditional procedures defined in the document are not implemented. Exceptions to this are the partial implementation of DEPARE02 DEPCNT03 LIGHTS05 and QUAPOS01.
• Complex line sets are not used.
• S52 symbols are displayed based on the SIMPLIFIED look up table.
• The styling of polygons and areas is limited to the polygon style supported. It is built based on the PLAIN_BOUNDARIES, LINES_SET or SIMPLIFIED look up tables.
• S52 symbols for lights are not rotated.
