SWFGradient->__construct()

(PHP 5)

SWFGradient->__construct() — Creates a gradient object

Description

SWFGradient

SWFGradient __construct ( void )

Warning

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);

  $s->drawLine(0, 240);

  $s->drawLine(-320, 0);

  $s->drawLine(0, -240);



  $m->add($s);



  header('Content-type: application/x-shockwave-flash');

  $m->output();
