Hi Listers,
I am working with MapXtreme3.0 for Java and quite new to it. I am trying to
add a simple layer(of blue color) over a GST. I can see only the gst but not
the layer...!
this is what i am doing
myMap = new MapJ();
myMap.setDeviceBounds(new DoubleRect(0, 0, 400, 400));
AnnotationDataProviderHelper DPHelper = new AnnotationDataProviderHelper();
AnnotationTableDescHelper TabDesc = new AnnotationTableDescHelper("LA");
LocalDataProviderRef MXDPRef = new LocalDataProviderRef(DPHelper);
Layer LALayer = myMap.getLayers().insert(MXDPRef, TabDesc, 0, "LA");
FeatureFactory ff = myMap.getFeatureFactory();
Attribute att1[] = new Attribute[1];
Rendition rend = new Rendition();
att1[0] = new Attribute("Feature1");
rend.setValue(Rendition.FILL, java.awt.Color.blue);
rend.setValue(Rendition.FILL_OPACITY, new Float(0.1));
double pnts[] = {-200,-200, 200,-200, 200,200, -200,200 };
LALayer.addFeature(ff.createRegion(pnts, rend, att1, null));
String MapXURL = "<http://localhost:8080/mapxtreme/servlet/MapX>";
myMap.loadGeoset("c:\\mapinfo\\data\\gb.gst", "c:\\mapinfo\\data", MapXURL);
MapXtremeImageRenderer renderer = new MapXtremeImageRenderer(MapXURL);
myMap.render(renderer);
res.setContentType("image/gif");
renderer.toStream(res.getOutputStream());
renderer.dispose();
if I remove the "myMap.loadGeoset(..." line, I can see the layer.
but if I add it I can see only the geoset, not the layer.
Can anyone tell how to do it or what wrong am i doing or how can I get it
right?
Thnx in advance
Sachin
