Hello,
I have a png that i load with Loader, but I need to copy it into a larger bitmap. I’m trying to use copyPixels but that works with BitmapData, my question is how do i put my loader into a BitmapData object?


var loader:Loader = new Loader();
loader.load( new URLRequest( "pic1.png" ) );

var bmpd:BitmapData = new BitmapData( 128,128,false,0xFFFFFF00 );
var bmp:Bitmap = new Bitmap( bmpd );
