The SVG Reader

There are two ways of reading SVG files:

Use an IlvMapSVGReader instance directly. When you use IlvMapSVGReader, you must write all of the code required to render the SVG features into graphic objects, and to add them to the manager.
Use an IlvSVGDataSource. This is a convenient way of performing all of the above operations at once. Using IlvSVGDataSource is better integrated with the data model of the map.

This section contains the following topics:

String SVGpath = " C:/maps/SVG/map.svg";

IlvMapSVGReader reader = new IlvMapSVGReader(SVGpath);

reader.setDestinationBounds(lonMinRad,latMinRad,lonMaxRad,latMaxRad);

IlvFeatureRenderer renderer = reader.getDefaultFeatureRenderer();

IlvMapFeature feature = reader.getNextFeature();

while(feature != null) {

  // Render map feature into a graphic object

  IlvGraphic graphic = renderer.makeGraphic(feature,null);

  // Add this object to the first layer of the manager

  manager.addObject(graphic, 0, false);

  feature = reader.getNextFeature();

The IlvSVGDataSource class provides a convenient way to create a set of layers containing SVG data in a manager.

Here are the steps required to read SVG features by means of the IlvSVGDataSource:

String SVGpath = "C:/maps/map.svg";

IlvSVGDataSource source = new IlvSVGDataSource(SVGpath);

source.setManager(getView().getManager());

source.setDestinationBounds(lonMinRad,latMinRad,lonMaxRad,latMaxRad);


 
   Note
 
 
     Alternatively you can use a tailored transformation by calling IlvSVGDataSource.setInternalTransformation.

source.start();
