使用IScreenDisplay实现
1
public static void FlashGeometry(IGeometry geometry, IScreenDisplay screenDisplay, IRgbColor rgbColor, Int32 delay)
2 
{
3
if (geometry == null || rgbColor == null || screenDisplay == null)
4
{
5 return;
6
}
7
8 screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
9
10 switch (geometry.GeometryType)
11 {
12 case ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryPolygon:
13 {
14 //Set the flash geometry's symbol.
15 ESRI.ArcGIS.Display.ISimpleFillSymbol simpleFillSymbol = new ESRI.ArcGIS.Display.SimpleFillSymbolClass();
16 simpleFillSymbol.Color = rgbColor;
17 ESRI.ArcGIS.Display.ISymbol symbol = simpleFillSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
18 symbol.ROP2 = ESRI.ArcGIS.Display.esriRasterOpCode.esriROPNotXOrPen;
19
20 //Flash the input polygon geometry.
21 screenDisplay.SetSymbol(symbol);
22 screenDisplay.DrawPolygon(geometry);
23 System.Threading.Thread.Sleep(delay);
24 screenDisplay.DrawPolygon(geometry);
25 break;
26 }
27
28 case ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryPolyline:
29 {
30 //Set the flash geometry's symbol.
31 ESRI.ArcGIS.Display.ISimpleLineSymbol simpleLineSymbol = new ESRI.ArcGIS.Display.SimpleLineSymbolClass();
32 simpleLineSymbol.Width = 4;
33 simpleLineSymbol.Color = rgbColor;
34 ESRI.ArcGIS.Display.ISymbol symbol = simpleLineSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
35 symbol.ROP2 = ESRI.ArcGIS.Display.esriRasterOpCode.esriROPNotXOrPen;
36
37 //Flash the input polyline geometry.
38 screenDisplay.SetSymbol(symbol);
39 screenDisplay.DrawPolyline(geometry);
40 System.Threading.Thread.Sleep(delay);
41 screenDisplay.DrawPolyline(geometry);
42 break;
43 }
44
45 case ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryPoint:
46 {
47 //Set the flash geometry's symbol.
48 ESRI.ArcGIS.Display.ISimpleMarkerSymbol simpleMarkerSymbol = new ESRI.ArcGIS.Display.SimpleMarkerSymbolClass();
49 simpleMarkerSymbol.Style = ESRI.ArcGIS.Display.esriSimpleMarkerStyle.esriSMSCircle;
50 simpleMarkerSymbol.Size = 12;
51 simpleMarkerSymbol.Color = rgbColor;
52 ESRI.ArcGIS.Display.ISymbol symbol = simpleMarkerSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
53 symbol.ROP2 = ESRI.ArcGIS.Display.esriRasterOpCode.esriROPNotXOrPen;
54
55 //Flash the input point geometry.
56 screenDisplay.SetSymbol(symbol);
57 screenDisplay.DrawPoint(geometry);
58 System.Threading.Thread.Sleep(delay);
59 screenDisplay.DrawPoint(geometry);
60 break;
61 }
62
63 case ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryMultipoint:
64 {
65 //Set the flash geometry's symbol.
66 ESRI.ArcGIS.Display.ISimpleMarkerSymbol simpleMarkerSymbol = new ESRI.ArcGIS.Display.SimpleMarkerSymbolClass();
67 simpleMarkerSymbol.Style = ESRI.ArcGIS.Display.esriSimpleMarkerStyle.esriSMSCircle;
68 simpleMarkerSymbol.Size = 12;
69 simpleMarkerSymbol.Color = rgbColor;
70 ESRI.ArcGIS.Display.ISymbol symbol = simpleMarkerSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
71 symbol.ROP2 = ESRI.ArcGIS.Display.esriRasterOpCode.esriROPNotXOrPen;
72
73 //Flash the input multipoint geometry.
74 screenDisplay.SetSymbol(symbol);
75 screenDisplay.DrawMultipoint(geometry);
76 System.Threading.Thread.Sleep(delay);
77 screenDisplay.DrawMultipoint(geometry);
78 break;
79 }
80 }
81 screenDisplay.FinishDrawing();
82
}
使用IIdentifyObj实现1
public static void FlashFeature2(IScreenDisplay screenDisplay, IFeature feature)2
{3
IFeatureIdentifyObj featureIdentifyObj = new ESRI.ArcGIS.CartoUI.FeatureIdentifyObjectClass();4
featureIdentifyObj.Feature = feature;5
6
IIdentifyObj identifyObj = featureIdentifyObj as IIdentifyObj;7
identifyObj.Flash(screenDisplay);8
}
Notice: IFeatureIdentifyObj接口的实例类FeatureIdentifyObjectClass的命名空间和接口的命名空间不同,接口为ESRI.ArcGIS.Carto,而实例类为ESRI.ArcGIS.CartoUI.
