### 返り値

### 例

例1 Object oriented style

`<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->setSourceRgb(0, 0, 0);
$c->paint();
$c->setSourceRgb(1, 1, 1);
$c->rectangle(0, 0, 50, 50);
$c->fill();
$c->setSourceRgb(0, 1, 0);
$c->rectangle(50, 50, 50, 50);
$c->fill();
$s->writeToPng(dirname(__FILE__) . '/CairoContext_fill.png');
?>`

例2 Procedural style

`<?php
$s = cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE, 100, 100);
$c = cairo_create($s);
cairo_set_source_rgb($c, 0, 0, 0);
cairo_paint($c);
cairo_set_source_rgb($c, 1, 1, 1);
cairo_rectangle($c, 0, 0, 50, 50);
cairo_fill($c);
cairo_set_source_rgb($c, 0, 1, 0);
cairo_rectangle($c, 50, 50, 50, 50);
cairo_fill($c);
cairo_surface_write_to_png($s, dirname(__FILE__) . '/cairo_fill.png');
?>`

上の例の出力は、 たとえば以下のようになります。
