Question

UGGeoPicture* geopicture = new UGGeoPicture();
    geopicture->SetAbsolutePath(_U(":/MapDemo/Resources/SelectPlane.png"));   
    geopicture->SetCenterPoint(pt2d); //此处pt2d是通过鼠标滚轮后计算出来的坐标
    geopicture->SetHeight(200);
    geopicture->SetWidth(200);
    m_pMapEditorWnd->m_mapWnd.m_Map.m_TrackingLayer.Add(geopicture, _U("tupian"));
    m_pMapEditorWnd->m_mapWnd.m_Map.SetRefreshFlag(true);  
    m_pMapEditorWnd->SendInvalidateFunc();

通过该方法我的图片并不能在地图上展示出来，请问我这里是哪里不正确吗？
