CairoContext::fill -- cairo_fill — Fills the current path
面向对象风格 (method):
过程化风格:
$context
)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.
context
A valid CairoContext object created with CairoContext::__construct() or cairo_create()
没有返回值。
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' );
?>
