CairoContext::copyPath -- cairo_copy_path — Creates a copy of the current path
面向对象风格 (method):
过程化风格:
$context
)Creates a copy of the current path and returns it to the user as a CairoPath. See CairoPath for hints on how to iterate over the returned data structure.
This function will always return a valid CairoPath object, but the result will have no data, if either of the following conditions hold:
context
is already in an error state.
In this case CairoPath->status will contain the same status that would be returned by
cairo_status() .
context
A valid CairoContext object created with CairoContext::__construct() or cairo_create()
A copy of the current CairoPath in the context
Example #1 面向对象风格
<?php
$surface = new CairoImageSurface ( CairoFormat :: ARGB32 , 50 , 50 );
$context = new CairoContext ( $surface );
var_dump ( $context -> copyPath ())
?>
以上例程的输出类似于:
object(CairoPath)#3 (0) { }
Example #2 过程化风格
<?php
$surface = cairo_image_surface_create ( CAIRO_FORMAT_ARGB32 , 50 , 50 );
$context = cairo_create ( $surface );
var_dump ( cairo_copy_path ( $context ));
?>
以上例程的输出类似于:
object(CairoPath)#3 (0) { }
