[helpstring("method AddPolyline")]
HRESULT AddPolyline([in] IMxDrawPoints* points, [in] IMxDrawResbuf* sWdiths, [in] IMxDrawResbuf* eWidths, [in] IMxDrawResbuf* bulges, [out,retval] IMxDrawPolyline** ppNewObj);|
参数 |
说明 |
|
[in] IMxDrawPoints* points |
多线段的端点数组 |
|
[in] IMxDrawResbuf* sWdiths |
多线段端点的开始宽度数组 |
|
[in] IMxDrawResbuf* eWidths |

例如: C#代码.
MxDrawDatabase database = (MxDrawDatabase)axMxDrawX1.GetDatabase();
IMxDrawBlockTableRecord blkRec = database.CurrentSpace();
MxDrawPoints P1 = new MxDrawPoints();
MxDrawResbuf wdiths = new MxDrawResbuf();
wdiths.AddDouble(2);
wdiths.AddDouble(3);
wdiths.AddDouble(4);
MxDrawResbuf wdithe = new MxDrawResbuf();
wdithe.AddDouble(2);
wdithe.AddDouble(3);
wdithe.AddDouble(4);
MxDrawResbuf bulges = new MxDrawResbuf();
bulges.AddDouble(2);
bulges.AddDouble(3);
bulges.AddDouble(4);
P1.Add(0, 0, 0);
P1.Add(100, 200, 0);
P1.Add(300, 100, 0);
blkRec.AddPolyline(P1, wdiths, wdithe, bulges);
