Re: [flexcoders] BitmapData Argument: Error #1063: Arg count mismatch on object util.copy

Probably something like:

        public function writeExternal(output:IDataOutput):void
       {
            output.writeInt(_bitmapData.width);
            output.writeInt(_bitmapData.height);
            output.writeBytes(_bitmapData.getPixels(new Rectangle(0, 0, 
_bitmapData.width, _bitmapData.height))
        }

        public function readExternal(input:IDataInput):vo! id
        {
            var w:int = input.readInt();
            var h:int = input.readInt();
        _bitmapData = new BitmapData(w, h);
        _bitmapData.setPixels(input.readBytes(), new Rectangle(0, 0, w, h));
        }

How would I go about implementing that? eg:

public class PageVO implements IExternalizable
{
        public function get bitmapData():BitmapData
        {
            return _bitmapData;
        }

        public function set bitmapData(value:BitmapData):void
        {
            _bitmapData = value;
        }

        public function writeExternal(output:IDataOutput):void
        {

        }

        public function readExternal(input:IDataInput):vo! id
        {
        }
}

   You can implement IExternalizable on the object that references the 
bitmapdata

I'm creating a deep copy of an object which has a BitmapData property using 
ObjectUtil.copy and 'registerClassAlias', eg:

registerClassAlias("flash.display.BitmapData", BitmapData);

...but I'm getting the error: ArgumentError: Error #1063: Argument count 
mismatch on flash.display::BitmapData(). Expected 2, got 0

Is there a workaround?

Thanks,

Philip
