Q:假设已经有 B的 bitmapdata (var :BitmapData = B;)和X的bitmapData(var bitmapData_X:BitmapData = C;),求A的bitmapdata_A
A: var bHalfWidth:Number = bitmapData_B.width/2; var xWidth:Number = bitmapData_X.width; var xHeight:Number = bitmapData_X.height; var scaledHeight:Number = bHalfWidth*2/3; var scaledWidth:Number = xWidth*scaledXHeight/xHeight; var scaledBitmapData:BitmapData = new BitmapData(scaledHeight,scaledWidth) var scale:Number = scaledHeight/xHeight; var matrix:Matrix = new Matrix(); matrix.createBox(scale,scale,-Math.PI/2,0,scaledWidth); scaledBitmapData.draw(new Bitmap(bitmapData_X),matrix); bitmapData_B.merge(scaledBitmapData,new Rectangle(0,0,scaledBitmapData.width,scaledBitmapData.height), new Point(bitmapData_B.width/2+5,(bitmapData_B.height-scaledBitmapData.height)/2),0xff,0xff,0xff,0xff);
