指北针

C#代码

public void AddNorthArrow(IPageLayout pageLayout)

       {

            IGraphicsContainer container = pageLayout as IGraphicsContainer;

            IActiveView activeView = pageLayout as IActiveView;

            // 获得MapFrame

            IFrameElement frameElement = container.FindFrame(activeView.FocusMap);

            IMapFrame mapFrame = frameElement as IMapFrame;

            //根据MapSurround的uid，创建相应的MapSurroundFrame和MapSurround

            UID uid = new UIDClass();

            uid.Value = "esriCarto.MarkerNorthArrow";

        IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null);

            //设置MapSurroundFrame中指北针的点符号

            IMapSurround mapSurround = mapSurroundFrame.MapSurround;

            IMarkerNorthArrow markerNorthArrow = mapSurround as IMarkerNorthArrow;

            IMarkerSymbol markerSymbol = markerNorthArrow.MarkerSymbol;

            markerSymbol.Size = 18;

            markerNorthArrow.MarkerSymbol = markerSymbol;

            //QI，确定mapSurroundFrame的位置

            IElement element = mapSurroundFrame as IElement;

            IEnvelope envelope = new EnvelopeClass();

            envelope.PutCoords(0.2, 0.2, 5, 5);

            element.Geometry = envelope;

            //使用IGraphicsContainer接口添加显示

            container.AddElement(element, 0);

            activeView.Refresh();

}

   比例尺

C#代码

public void AddScalebar(IPageLayout pageLayout)

        {

            IGraphicsContainer container = pageLayout as IGraphicsContainer;

            IActiveView activeView = pageLayout as IActiveView;

            // 获得MapFrame

            IFrameElement frameElement = container.FindFrame(activeView.FocusMap);

            IMapFrame mapFrame = frameElement as IMapFrame;

           //根据MapSurround的uid，创建相应的MapSurroundFrame和MapSurround

            UID uid = new UIDClass();

            uid.Value = "esriCarto.AlternatingScaleBar";

      IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null);

            //设置MapSurroundFrame中比例尺的样式

            IMapSurround mapSurround = mapSurroundFrame.MapSurround;

            IScaleBar markerScaleBar = ((IScaleBar)mapSurround);

            markerScaleBar.LabelPosition = esriVertPosEnum.esriBelow;

            markerScaleBar.UseMapSettings();

            //QI，确定mapSurroundFrame的位置

            IElement element = mapSurroundFrame as IElement;

            IEnvelope envelope = new EnvelopeClass();

            envelope.PutCoords(0.2, 0.2, 1, 2);

            element.Geometry = envelope;

            //使用IGraphicsContainer接口添加显示

            container.AddElement(element, 0);

            activeView.Refresh();

   }

   图例

C#代码

private void AddLegend(IPageLayout pageLayout)

       {

           IActiveView pActiveView = pageLayout as IActiveView;

           IGraphicsContainer container = pageLayout as IGraphicsContainer;

           // 获得MapFrame

       IMapFrame mapFrame = container.FindFrame(pActiveView.FocusMap) as IMapFrame;

           //根据MapSurround的uid，创建相应的MapSurroundFrame和MapSurround

           UID uid = new UIDClass();

           uid.Value = "esriCarto.Legend";

       IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null);

           //设置图例的Title

           ILegend2 legend = mapSurroundFrame.MapSurround as ILegend2;

           legend.Title = "地图图例";

           ILegendFormat format = new LegendFormatClass();

           ITextSymbol symbol = new TextSymbolClass();

           symbol.Size = 4;

           format.TitleSymbol = symbol;

           legend.Format = format;

           //QI，确定mapSurroundFrame的位置

           IElement element = mapSurroundFrame as IElement;

           IEnvelope envelope = new EnvelopeClass();

           envelope.PutCoords(2, 2, 8, 8);

           element.Geometry = envelope;

           //使用IGraphicsContainer接口添加显示

           container.AddElement(element, 0);

           pActiveView.Refresh();

}
