一个简单得问题

<P>代码如下：</P>
<P> <BR>   //GraphicList里面存放的是一个polyLINE里所有的图形<BR>   private IGeometry getMulRect(GraphicList list) throws UnknownHostException, IOException<BR> {<BR>  Polyline pg = null;<BR>  pg = new Polyline();<BR>  IGeometryCollection gcc =pg.getAsIGeometryCollection() ;<BR>  int size = list.size();<BR>  IPointCollection pcc = new IPointCollectionProxy( pg);<BR>  for(int i = 0;i<size;i++)<BR>  {<BR>   Path seg = new Path();<BR>   IPointCollection pc = new IPointCollectionProxy( seg);<BR>   //自己的程序，可以得到里面的点的坐标<BR>   Rect poly = (Rect)list.getGraphicAt(i);<BR>   getPoly(poly,pc);<BR>   pcc.addPointCollection(pc);</P>
<P>  }</P>
<P> <BR>  return pg.getAsIGeometry();</P>
<P> }</P>
<P><BR> // poly,基本图形为几个矩形<BR> public void getPoly(Graphic pp,IPointCollection pc) throws UnknownHostException,<BR>   IOException<BR> {<BR>   if(pp instanceof Rect)<BR>  {<BR>   Rect rect = ( Rect)pp;<BR>   IPoint p1 = new Point();<BR>   p1.setY( rect.getNorthLat());<BR>   p1.setX( rect.getEastLon());<BR>   IPoint p2 = new Point();<BR>   p2.setY( rect.getNorthLat());<BR>   p2.setX( rect.getWestLon());<BR>   IPoint p3 = new Point();<BR>   p3.setY( rect.getSouthLat());<BR>   p3.setX( rect.getWestLon());<BR>   IPoint p4 = new Point();<BR>   p4.setY( rect.getSouthLat());<BR>   p4.setX( rect.getEastLon());<BR>   </P>
<P>   pc.addPoint(   p2, null, null);  <BR>   pc.addPoint(   p3, null, null); <BR>   pc.addPoint(   p4, null, null); <BR>   pc.addPoint(   p1, null, null); <BR>   pc.addPoint(   p2, null, null); </P>
<P>  }</P>
<P> }<BR></P>

<P>我传入得是四个不相连得矩形，为什么用这个程序执行起来，四个矩形都被连接起来了呢，哪位大侠帮忙看看</P>

ding

四个矩形是怎么的连起来了呀？ 我没有明白。

没有人知道?我再顶

我来顶你，兄弟

<P>原图形是这样的：</P>
<P></P>
<P>用AE转换好成这样了：</P>
<P></P>
<P>有人知道为什么吗？</P>
