1、添加图例、比例尺、指北针代码中有注释，直接上 指北针C#代码 1 public void AddNorthArrow(IPageLayout pageLayout) 2 3 IGraphicsContainer container = pageLayout as IGraphicsContainer; 4 IActiveView activeView = pageLayout as IActiveView; 5 / 获得MapFrame 6 IFrameElement frameElement = container.FindFrame(activeView.FocusMap); 7 IMap

2、Frame mapFrame = frameElement as IMapFrame; 8 /根据MapSurround的uid，创建相应的MapSurroundFrame和MapSurround 9 UID uid = new UIDClass(); 10 uid.Value = esriCarto.MarkerNorthArrow; 11 IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null); 12 /设置MapSurroundFrame中指北针的点符号 13 IMapSurround ma

3、pSurround = mapSurroundFrame.MapSurround; 14 IMarkerNorthArrow markerNorthArrow = mapSurround as IMarkerNorthArrow; 15 IMarkerSymbol markerSymbol = markerNorthArrow.MarkerSymbol; 16 markerSymbol.Size = 18; 17 markerNorthArrow.MarkerSymbol = markerSymbol; 18 /QI，确定mapSurroundFrame的位置 19 IElement elem

4、ent = mapSurroundFrame as IElement; 20 IEnvelope envelope = new EnvelopeClass(); 21 envelope.PutCoords(0.2, 0.2, 5, 5); 22 element.Geometry = envelope; 23 /使用IGraphicsContainer接口添加显示 24 container.AddElement(element, 0); 25 activeView.Refresh(); 26 比例尺C#代码 27 public void AddScalebar(IPageLayout pageL

5、ayout) 28 29 IGraphicsContainer container = pageLayout as IGraphicsContainer; 30 IActiveView activeView = pageLayout as IActiveView; 31 / 获得MapFrame 32 IFrameElement frameElement = container.FindFrame(activeView.FocusMap); 33 IMapFrame mapFrame = frameElement as IMapFrame; 34 /根据MapSurround的uid，创建相应

6、的MapSurroundFrame和MapSurround 35 UID uid = new UIDClass(); 36 uid.Value = esriCarto.AlternatingScaleBar; 37 IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null); 38 /设置MapSurroundFrame中比例尺的样式 39 IMapSurround mapSurround = mapSurroundFrame.MapSurround; 40 IScaleBar markerScale

7、Bar = (IScaleBar)mapSurround); 41 markerScaleBar.LabelPosition = esriVertPosEnum.esriBelow; 42 markerScaleBar.UseMapSettings(); 43 /QI，确定mapSurroundFrame的位置 44 IElement element = mapSurroundFrame as IElement; 45 IEnvelope envelope = new EnvelopeClass(); 46 envelope.PutCoords(0.2, 0.2, 1, 2); 47 elem

8、ent.Geometry = envelope; 48 /使用IGraphicsContainer接口添加显示 49 container.AddElement(element, 0); 50 activeView.Refresh(); 51 图例C#代码 52 private void AddLegend(IPageLayout pageLayout) 53 54 IActiveView pActiveView = pageLayout as IActiveView; 55 IGraphicsContainer container = pageLayout as IGraphicsContai

9、ner; 56 / 获得MapFrame 57 IMapFrame mapFrame = container.FindFrame(pActiveView.FocusMap) as IMapFrame; 58 /根据MapSurround的uid，创建相应的MapSurroundFrame和MapSurround 59 UID uid = new UIDClass(); 60 uid.Value = esriCarto.Legend; 61 IMapSurroundFrame mapSurroundFrame = mapFrame.CreateSurroundFrame(uid, null);

10、62 /设置图例的Title 63 ILegend2 legend = mapSurroundFrame.MapSurround as ILegend2; 64 legend.Title = 地图图例; 65 ILegendFormat format = new LegendFormatClass(); 66 ITextSymbol symbol = new TextSymbolClass(); 67 symbol.Size = 4; 68 format.TitleSymbol = symbol; 69 legend.Format = format; 70 /QI，确定mapSurroundFrame的位置 71 IElement element = mapSurroundFrame as IElement; 72 IEnvelope envelope = new EnvelopeClass(); 73 envelope.PutCoords(2, 2, 8, 8); 74 element.Geometry = envelope; 75 /使用IGraphicsContainer接口添加显示 76 container.AddElement(element, 0); 77 pActiveView.Refresh(); 78
