CairoContext::copyPathFlat
cairo_copy_path_flat
(PECL cairo >= 0.1.0)
CairoContext::copyPathFlat -- cairo_copy_path_flat — Gets a flattened copy of the current path
説明
オブジェクト指向型 (method):
手続き型:
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.
パラメータ
-
context -
A CairoContext object
返り値
A copy of the current path
例
例1 オブジェクト指向型
<?php
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
$context = new CairoContext($surface);
var_dump($context->copyPathFlat());
?>
上の例の出力は、 たとえば以下のようになります。
object(CairoPath)#3 (0) {
}
例2 手続き型
<?php
$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
$context = cairo_create($surface);
var_dump(cairo_copy_path_flat($context));
?>
上の例の出力は、 たとえば以下のようになります。
object(CairoPath)#3 (0) {
}

- CairoContext::copyPath() - Creates a copy of the current path
- CairoContext::closePath() - Closes the current path
