CairoContext::copyPath

cairo_copy_path

(PECL cairo >= 0.1.0)

CairoContext::copyPath -- cairo_copy_pathCreates a copy of the current path

Description

Object oriented style (method):

public CairoPath CairoContext::copyPath ( void )

Procedural style:

CairoPath cairo_copy_path ( CairoContext $context )

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 context is already in an error state. In this case CairoPath->status will contain the same status that would be returned by cairo_status().
In either case, CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY (regardless of what the error status in cr might have been).

Parameters

context

A valid CairoContext object created with CairoContext::__construct() or cairo_create()

Return Values

A copy of the current CairoPath in the context

Examples

Example #1 Object oriented style

<?php

$surface 
= new CairoImageSurface(CairoFormat::ARGB325050);

$context = new CairoContext($surface);

var_dump($context->copyPath())

?>

The above example will output something similar to:

object(CairoPath)#3 (0) {
}

Example #2 Procedural style

<?php

$surface 
cairo_image_surface_create(CAIRO_FORMAT_ARGB325050);

$context cairo_create($surface);

var_dump(cairo_copy_path($context));

?>

The above example will output something similar to:

object(CairoPath)#3 (0) {
}
