地图整饰-添加地图框架元素

添加地图框架元素

知识拓展：http://blog.csdn.net/summer_dew/article/details/79187995

思路：

1. 获取PageLayout对象

   IPageLayout pPageLayout = axPageLayoutControl1.PageLayout;
   

2. 获取活动视图ActiveView

   IActiveView pActiveView = axPageLayoutControl1.ActiveView;
   

3. 获取图形容器GraphicsContainer

   IGraphicsContainer pGraphicsContainer = pPageLayout as IGraphicsContainer;
   

4. 找到MapFrame（地图框架）对象

   IMapFrame pMapFrame = pGraphicsContainer.FindFrame(pActiveView.FocusMap) as IMapFrame;
   

5. 创建MapSurroundFrame对象（创建图例）

   UID pUid = new UIDClass();
   pUid.Value = "esriCarto.Legend";
   IMapSurroundFrame pMapSurroundFrame = pMapFrame.CreateSurroundFrame(pUid,null);
   

6. 添加MapSurroundFrame的空间位置

   IElement pElement = pMapSurroundFrame as IElement;
   pElement.Geometry = axPageLayoutControl1.TrackRectangle();
   

7. 将元素添加到容器中

   pGraphicsContainer.AddElement(pElement,0);
   

8. 刷新

   axPageLayoutControl1.Refresh();
   

代码：

int pageFlag = -1;
//PageLayout点击事件
private void axPageLayoutControl1_OnMouseDown(object sender, IPageLayoutControlEvents_OnMouseDownEvent e)
{
    if (e.button == 1)
    {
        return;
    }
    else if (e.button == 2)
    {
        switch (pageFlag)
        {
            case 1: //图名
                {
                    //找到PageLayout
                    IPageLayout pPageLayout = axPageLayoutControl1.PageLayout;
                    //找到元素容器
                    IGraphicsContainer pGraphicsContainer = pPageLayout as IGraphicsContainer;
                    //创建元素
                    ITextElement pTextElement = new TextElementClass();
                    pTextElement.Text = "世界地图";
                    ITextSymbol pTextSymbol = new TextSymbolClass();
                    pTextSymbol.Size = 30;
                    pTextSymbol.Color = GetRGB(255, 0, 0);
                    pTextElement.Symbol = pTextSymbol;
                    //设置位置                        
                    IElement pElement = pTextElement as IElement;
                    pElement.Geometry = axPageLayoutControl1.TrackRectangle();
                    //将元素添加到容器中
                    pGraphicsContainer.AddElement(pElement, 0);
                    //刷新
                    axPageLayoutControl1.Refresh();
                    break;
                }
            case 2: //比例尺
                {
                    IPageLayout pPageLayout = axPageLayoutControl1.PageLayout;
                    IActiveView pActiveView = axPageLayoutControl1.ActiveView;
                    IGraphicsContainer pGraphicsContainer = pPageLayout as IGraphicsContainer;
                    IMapFrame pMapFrame = pGraphicsContainer.FindFrame(pActiveView.FocusMap) as IMapFrame;
                    UID pUid = new UIDClass();
                    pUid.Value = "esriCato.AlternatingScaleBar";
                    IMapSurroundFrame pMapSurroundFrame = pMapFrame.CreateSurroundFrame(pUid, null);
                    IElement pElement = pMapSurroundFrame as IElement;
                    pElement.Geometry = axPageLayoutControl1.TrackRectangle();
                    pGraphicsContainer.AddElement(pElement, 0);
                    axPageLayoutControl1.Refresh();
                    break;
                }

                    pGraphicsContainer.AddElement(pElement, 0);
                    axPageLayoutControl1.Refresh();
                    break;
                }
            case 4: //指北针
                {
                    IPageLayout pPageLayout = axPageLayoutControl1.PageLayout;
                    IActiveView pActiveView = axPageLayoutControl1.ActiveView;
