flex内阴影效果

记录一下，AS代码如下： private function getBitmapFilter():BitmapFilter { ??? var color:Number = 0x96c2e6; ??? var alpha:Number = 0.8; ??? var blurX:Number = 5; ??? var blurY:Number = 5; ??? var strength:Number = 2; ??? var inner:Boolean = true; ??? var knockout:Boolean = false; var quality:Number = BitmapFilterQuality.HIGH; ??? return new GlowFilter(color,????????????????????????? alpha,????????????????????????? blurX,????????????????????????? blurY,????????????????????????? strength,????????????????????????? quality,????????????????????????? inner,????????????????????????? knockout); } 设置组件的filters属性，组件要设置边框和背景色样式才能看得出，下面是示例： ??? <mx:Canvas width="300" height="200" filters="{[getBitmapFilter()]}" ??????? borderStyle="solid" backgroundColor="#FFFFFF"/> 可适当调节一些参数值来改变内阴影的效果。
