CairoContext::copyPathFlat -- cairo_copy_path_flat — Gets a flattened copy of the current path

说明

面向对象风格 (method):

public CairoContext::copyPathFlat ( void ) : CairoPath

过程化风格:

cairo_copy_path_flat ( CairoContext $context ) : CairoPath

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.

参数

context: A CairoContext object

返回值

A copy of the current path

范例

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) {
}
