CairoContext::fill()

(PECL cairo >= 0.1.0)

Fills the current path

说明

面向对象风格(method):

publicCairoContext::fill(void): void

过程化风格:

cairo_fill(CairoContext$context): void

A drawing operator that fills the current path according to the current CairoFillRule,(each sub-path is implicitly closed before being filled). After CairoContext::fill() or cairo_fill(), the current path will be cleared from the CairoContext.

参数

$context: A valid CairoContext object created with CairoContext::__construct() or cairo_create()

返回值

没有返回值。

范例

Example #1 面向对象风格

<?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');
?>

以上例程的输出类似于：

Example #2 过程化风格

<?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');
?>

以上例程的输出类似于：
