<?php

  $b = new SWFBitmap("backyard.jpg");
  // 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();
