SWFGradient->__construct()

Creates a gradient object ()

SWFGradient {
  SWFGradient __construct();
}
Warning:

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.

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 1342. 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);
