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.
例子 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();
?>
