请教 --- LENS.IDEAL

<P>我用LENS IDEAL 定义半波片，但波片的形状总是圆的，要如何改变成长方形的呢？</P>
<img src="data/attachment/forum/dvbbs/2004-10/200410891543502.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'data/attachment/forum/dvbbs/2004-10/200410891543502.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

自己定义一个需要的孔阑是个比较快的方法。

<P>小马兄，</P><P>能说详细一些吗？</P><P>谢</P>

做一个Mask,你需要什么样的形状就MASK成什么形状

<P>小马兄，</P><P>能有相关的例子参考一下吗?</P><P>谢了</P>
