void swfdisplayitem->multcolor ( int red, int green, int blue [, int a] )


This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

swfdisplayitem->multcolor() multiplies the item's color transform by the given values.

The object may be a swfshape(), a swfbutton(), a swftext() or a swfsprite() object. It must have been added using the swfmovie->add().

This simple example will modify your picture's atmosphere to Halloween (use a landscape or bright picture).

Example 1. swfdisplayitem->multcolor() example


  $b = new SWFBitmap(file_get_contents("backyard.jpg"));
  // note use your own picture :-)
  $s = new SWFShape();
  $s->drawLine($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);
