CairoContext::fill -- cairo_fill — Fills the current path
Object oriented style (method):
Procedural style:
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.
没有返回值。
Example #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');
?>

Example #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');
?>
