oh btw jody, if i already create referencedenvelope so where i must put it and how to set it?
am i must set the featureSource with ReferencedEnvelope after this code
featureSource = store.getFeatureSource();
and is this the right method for it?
FeatureCollection grabFeaturesInBoundingBox( double x1, double y1, double x2, double y2) throws Exception {
FilterFactory2 ff = CommonFactoryFinder.getFilterFactory2( null );
FeatureType schema = featureSource.getSchema();
// usually "THE_GEOM" for shapefiles
String geometryPropertyName = schema.getGeometryDescriptor().getLocalName();
CoordinateReferenceSystem crs = schema.getGeometryDescriptor().getCoordinateReferenceSystem();
ReferencedEnvelope bbox = new ReferencedEnvelope( x1,y1, x2, y2, crs );
Filter filter = ff.bbox( ff.property( geometryPropertyName ), bbox );
return featureSource.getFeatures( filter );
}
sorry for troubling you. i still not understand about this ReferencedEnvelope.
i hope i didn't bored you because i ask too much question :)
thank you

You can change the "Extent" or Bounds of your map context. Use new
ReferencedEnvelope( ... ) to sort out the area of the world you want
to show.
