CairoContext::fill

cairo_fill

(PECL cairo >= 0.1.0)

CairoContext::fill -- cairo_fill — Fills the current path

说明

面向对象风格 (method):

public void CairoContext::fill ( void )

过程化风格:

void cairo_fill ( CairoContext $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.

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' );

 ?>

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' );

 ?>
