SWFGradient::__construct — Creates a gradient object
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.
swfgradient() creates a new SWFGradient object.
After you've added the entries to your gradient, you can use the gradient in a shape fill with the swfshape::addfill() method.
SWFGradient has the following methods : swfgradient::addentry().
This simple example will draw a big black-to-white gradient as background, and a reddish disc in its center.
Example #1 swfgradient() example
<?php
  $m = new SWFMovie();
  $m->setDimension(320, 240);
  $s = new SWFShape();
  // first gradient- black to white
  $g = new SWFGradient();
  $g->addEntry(0.0, 0, 0, 0);
  $g->addEntry(1.0, 0xff, 0xff, 0xff);
  $f = $s->addFill($g, SWFFILL_LINEAR_GRADIENT);
  $f->scaleTo(0.01);
  $f->moveTo(160, 120);
  $s->setRightFill($f);
  $s->drawLine(320, 0);
  $s->drawLine(0, 240);
  $s->drawLine(-320, 0);
  $s->drawLine(0, -240);
  $m->add($s);
  $s = new SWFShape();
  // second gradient- radial gradient from red to transparent
  $g = new SWFGradient();
  $g->addEntry(0.0, 0xff, 0, 0, 0xff);
  $g->addEntry(1.0, 0xff, 0, 0, 0);
  $f = $s->addFill($g, SWFFILL_RADIAL_GRADIENT);
  $f->scaleTo(0.005);
  $f->moveTo(160, 120);
  $s->setRightFill($f);
  $s->drawLine(320, 0);
