Class WebPictureMarkerSymbol

java.lang.Object
  com.esri.adf.web.data.symbol.WebSymbol
      com.esri.adf.web.data.symbol.WebPictureMarkerSymbol

All Implemented Interfaces:

Serializable

public class WebPictureMarkerSymbol
extends WebSymbol
implements Serializable

WebPictureMarkerSymbol is a class used to symbolize point features. This symbol can be created using one of the following, byte[], URL, file name or a BufferedImage.

If multiple set methods are used then the following order is used to draw the symbol,

 1. getPicture()
 2. getURL()
 3. getImage()
 4. getFileName().
 
 For example,
   WebMultiPoint points = new WebMultiPoint();
   points.addPoint(new WebPoint(50, 50));
   points.addPoint(new WebPoint(100, 50));
   points.addPoint(new WebPoint(100, 100));
   points.addPoint(new WebPoint(50, 100));
 
   WebPictureMarkerSymbol pms = new WebPictureMarkerSymbol();
   pms.setAngle(45.0);
   pms.setFileName("c:/images/myImage.png");
 
   GraphicElement element = new GraphicElement();
   element.setGeometry(points);
   element.setSymbol(pms);
 
   WebElementConverter converter = new WebElementConverter(150, 150);
   converter.draw(element);
   byte[] image = converter.getPNGImage();
 

Warning: The image property of this symbol is not Serializable.
