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.

範例 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();
