Can you use BitmapData.generateFilterRect ? "Determines the destination rectangle that the applyFilter() method call affects, given a BitmapData object, a source rectangle, and a filter object. For example, a blur filter normally affects an area larger than the size of the original image. A 100 x 200 pixel image that is being filtered by a default BlurFilter instance, where blurX = blurY = 4 generates a destination rectangle of (-2,-2,104,204). The generateFilterRect() method lets you find out the size of this destination rectangle in advance so that you can size the destination image appropriately before performing a filter operation." -David R _______________________________________________ Flashcoders mailing list [email protected] http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
