CairoContext::copyPath
cairo_copy_path
(PECL cairo >= 0.1.0)
CairoContext::copyPath -- cairo_copy_path — Creates a copy of the current path
说明
面向对象风格 (method):
过程化风格:
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:
- 1. If there is insufficient memory to copy the path. In this case CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY.
- 2. If
contextis already in an error state. In this case CairoPath->status will contain the same status that would be returned by cairo_status().
返回值
A copy of the current CairoPath in the context
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->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) {
}
