I wonder whether it scales the filters. Go-go gadget "testbed" project...
... Time passes :) At first glance, it seems that filters are applied after scaling, but stroke widths don't get below 1 pixel: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="cc()"> <mx:Script> <![CDATA[ protected function cc() : void { drawIn(b1, 0xff); drawIn(b2, 0xffff); drawIn(b3, 0xffff00); } protected function drawIn(box : Canvas, bg : Number) : void { box.graphics.clear(); box.graphics.moveTo(0,0); box.graphics.beginFill(bg,1); box.graphics.drawRect(0,0,100,100); box.graphics.endFill(); box.graphics.moveTo(0,0); box.graphics.lineStyle(1,0,1); box.graphics.lineTo(100,100); box.graphics.moveTo(0,50); box.graphics.lineTo(100,50); box.graphics.moveTo(50,0); box.graphics.lineTo(50,100); } ]]> </mx:Script> <mx:Canvas horizontalCenter="0" verticalCenter="0" width="100" height="100" id="b2"> <mx:filters> <mx:DropShadowFilter alpha="0.8" blurX="0" blurY="0" angle="90" distance="15"/> </mx:filters> </mx:Canvas> <mx:Canvas horizontalCenter="-120" verticalCenter="0" width="100" height="100" id="b1"> <mx:filters> <mx:DropShadowFilter alpha="0.8" blurX="0" blurY="0" angle="90" distance="15"/> </mx:filters> </mx:Canvas> <mx:Canvas horizontalCenter="120" verticalCenter="0" width="100" height="100" id="b3"> <mx:filters> <mx:DropShadowFilter alpha="0.8" blurX="0" blurY="0" angle="90" distance="15"/> </mx:filters> </mx:Canvas> <mx:Button label="Scale" horizontalCenter="0" verticalCenter="-80" click="b1.scaleX=0.5;b1.scaleY=0.5;b3.scaleX=2;b3.scaleY=2"/> </mx:Application> On Wed, May 28, 2008 at 10:02 AM, Alex Harui <[EMAIL PROTECTED]> wrote: > I'm not sure what the player does for filtering.
