CairoContext::closePath -- cairo_close_path — Closes the current path
面向对象风格 (method):
过程化风格:
$context
)Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to CairoContext::moveTo() ), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path.
The behavior of close_path() is distinct from simply calling CairoContext::lineTo() with the equivalent coordinate in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead, there is a line join connecting the final and initial segments of the sub-path.
If there is no current point before the call to CairoContext::closePath() , this function will have no effect.

Example #1 面向对象风格
<?php
$surface = new CairoImageSurface ( CairoFormat :: ARGB32 , 50 , 50 );
$context = new CairoContext ( $surface );
$context -> closePath ();
?>
Example #2 过程化风格
<?php
$surface = cairo_image_surface_create ( CAIRO_FORMAT_ARGB32 , 50 , 50 );
$context = cairo_create ( $surface );
cairo_close_path ( $context );
