CairoContext::copyPathFlat -- cairo_copy_path_flat — Gets a flattened copy of the current path
面向对象风格 (method):
过程化风格:
$context
)Gets a flattened copy of the current path and returns it to the user as a CairoPath.
This function is like CairoContext::copyPath() except that any curves in the path will be approximated with piecewise-linear approximations, (accurate to within the current tolerance value). That is, the result is guaranteed to not have any elements of type CAIRO_PATH_CURVE_TO which will instead be replaced by a series of CAIRO_PATH_LINE_TO elements.
context
A CairoContext object
A copy of the current path
Example #1 面向对象风格
<?php
$surface = new CairoImageSurface ( CairoFormat :: ARGB32 , 50 , 50 );
$context = new CairoContext ( $surface );
var_dump ( $context -> copyPathFlat ());
?>
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_flat ( $context ));
?>
以上例程的输出类似于:
object(CairoPath)#3 (0) { }
