// note use your own picture :-)
$s = new SWFShape();
$s->setRightFill($s->addFill($b));
$s->drawLine($b->getWidth(), 0);
$s->drawLine(0, $b->getHeight());
$s->drawLine(-$b->getWidth(), 0);
$s->drawLine(0, -$b->getHeight());
$m = new SWFMovie();
$m->setDimension($b->getWidth(), $b->getHeight());
$i = $m->add($s);
for ($n=0; $n<=20; ++$n) {
$i->multColor(1.0-$n/10, 1.0, 1.0);
$i->addColor(0xff*$n/20, 0, 0);
$m->nextFrame();
