SWFGradient

(PHP 4 >= 4.0.5)

SWFGradient -- Creates a gradient object

Description

new swfgradient (void)

Warning

This function is EXPERIMENTAL. That means, that the behaviour of this function, this function name, in concreto ANYTHING documented here can change in a future release of PHP WITHOUT NOTICE. Be warned, and use this function 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 redish 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);
  $s->drawLine(0, 240);
  $s->drawLine(-320, 0);
  $s->drawLine(0, -240);

  $m->add($s);

  header('Content-type: application/x-shockwave-flash');
  $m->output();
?>
