范例

Example #1 面向对象风格

<?php

$s 
= new CairoImageSurface(CairoFormat::ARGB32100100);
$c = new CairoContext($s);
 
$c->setSourceRgb(000);
$c->paint();

$c->setSourceRgb(111);
$c->rectangle(005050);
$c->fill();
$c->setSourceRgb(010);
$c->rectangle(50505050);

cairo_paint($c);

cairo_set_source_rgb($c111);
cairo_rectangle($c005050);
cairo_fill($c);
