Class ExternalGraphic

java.lang.Object
  org.deegree.graphics.sld.ExternalGraphic

All Implemented Interfaces:

Marshallable

public class ExternalGraphic
extends Object
implements Marshallable

The ExternalGraphic element allows a reference to be made to an external graphic file with a Web URL. The OnlineResource sub-element gives the URL and the Format sub-element identifies the expected document MIME type of a successful fetch. Knowing the MIME type in advance allows the styler to select the best- supported format from the list of URLs with equivalent content.
