我有<p:gmap>
个特定标记。我想裁剪<p:gmap>
的一部分。我无法使用<p:imageCropper>
,因为它会裁剪图像,而不是谷歌地图。如何捕获Google地图的特定部分?
这是我的地图bean:
@ManagedBean
@ViewScoped
public class InfoWindowView implements Serializable {
private static final long serialVersionUID = 1L;
@EJB
GestionAnalyseLocal m;
private MapModel advancedModel;
private Marker marker;
@PostConstruct
public void init() throws IOException {
advancedModel = new DefaultMapModel();
List<Analyse> alys = new ArrayList<Analyse>();
alys = m.findAll();
for (int i = 2; i <= alys.size(); i++) {
Double x = null;
Double y = null;
try {
x = Double.parseDouble(alys.get(i).getLongitude());
y = Double.parseDouble(alys.get(i).getLatitude());
LatLng coord1 = new LatLng(y, x);
if (alys.get(i).getUu_HandoffOk() == 1) {
advancedModel.addOverlay(new Marker(coord1, "test", "point.png",
"http://maps.gstatic.com/mapfiles/ridefinder-images/mm_20_blue.png "));
} else {
if (alys.get(i).getUu_OutgoingCallOk() == 1) {
advancedModel.addOverlay(new Marker(coord1, "test", "phone",
"http://maps.google.com/mapfiles/kml/pal4/icon52.png"));
}
}
} catch (Exception e) {
System.out.println("err");
}
}
}
public MapModel getAdvancedModel() {
return advancedModel;
}
public void onMarkerSelect(OverlaySelectEvent event) {
marker = (Marker) event.getOverlay();
}
public Marker getMarker() {
return marker;
}
}

通过裁剪地图,您的意思是您仍然需要所有地图设施,但对于所选地区,您可以执行this之类的操作(当用户尝试裁剪地图并从原始地图构建中获取坐标时,请拍摄另一个地图将所选区域设置为新地图并向用户显示)用户仍然可以使用地图设施。
