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:
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) {
}
