This example uses a BitmapDataZone to create the fire in the same area as the logo. The fire effect is created from elliptical particles that fade in when they start and out again as they die and orient with their pointy end in the direction of motion.

var bitmapData:BitmapData = new Logo( 265, 80);
var bitmap:Bitmap = new Bitmap();
bitmap.bitmapData = bitmapData;
addChild( bitmap );
bitmap.x = 118;
bitmap.y = 70;

var emitter:Emitter2D = new Emitter2D();
emitter.counter = new Steady( 600 );

emitter.addInitializer( new Lifetime( 0.8 ) );
emitter.addInitializer( new Velocity( new DiscSectorZone( new Point( 0, 0 ), 10, 5, -Math.PI * 0.75, -Math.PI * 0.25 ) ) );
emitter.addInitializer( new Position( new BitmapDataZone( bitmapData ) ) );
emitter.addInitializer( new ImageClass( FireBlob ) );

emitter.addAction( new Age( TwoWay.quadratic ) );
emitter.addAction( new Move() );
emitter.addAction( new Accelerate( 0, -20 ) );
emitter.addAction( new ColorChange( 0xFFFF9900, 0x00FFDD66 ) );
emitter.addAction( new ScaleImage( 1.4, 2.0 ) );
emitter.addAction( new RotateToDirection() );

var renderer:BitmapRenderer = new BitmapRenderer( new Rectangle( 0, 0, 500, 200 ) );
renderer.addEmitter( emitter );
addChild( renderer );

emitter.x = 118;
emitter.y = 70;
emitter.start( );
