Cairo example and installation

[wepnop]

Im looking to use this library but if i use this sample:

<?php
// test_cairo.php
$s = new CairoImageSurface(CairoFormat::ARGB32, 400, 400);
$c = new CairoContext($s);
$c->fill();
$c->setSourceRGB(1, 0, 0);
$c->setLineWidth(50);
$c->arc(200, 200, 100, 0, 2 * M_PI);
$c->stroke();
$c->setSourceRGB(0, 0, 0.6);
$c->rectangle(0, 160, 400, 75);
$c->fill();

$s->writeToPng(dirname(__FILE__)  . '/test.png');

 

It dont works, seems undefined, and checking for the url that php manuals tells to visit i dont work:

Did you include the Class definitions that are part of that library into your code before you attempted to create the instances of the Classes?

Are those requirements fulfilled? Did you install the library or not?

      Hello all,

 

      This code comes from http://cambiatablog.wordpress.com/2010/11/06/getting-started-with-cairo-graphics-and-php/

 

     So, it means that the library these classes come from are part of WordPress. I think that WordPress is a free software.

 

      Hoping that it will help, cheers
