(PHP 4 >= 4.0.5)

SWFGradient -- Creates a gradient object

Description

object swfgradient ( void )

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 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();
