CairoContext::copyPath

cairo_copy_path

(PECL cairo >= 0.1.0)

CairoContext::copyPath -- cairo_copy_path — Creates a copy of the current path

Opis

Styl obiektowy (method):

public CairoPath CairoContext::copyPath ( void )

Styl proceduralny:

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).

Parametry

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

Zwracane wartości

A copy of the current CairoPath in the context

Przykłady

Przykład #1 Styl obiektowy


<?php

$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);

$context = new CairoContext($surface);

var_dump($context->copyPath())

?>

Powyższy przykład wyświetli coś podobnego do:

object(CairoPath)#3 (0) {
}

Przykład #2 Styl proceduralny


<?php

$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);

$context = cairo_create($surface);

var_dump(cairo_copy_path($context));

?>

Powyższy przykład wyświetli coś podobnego do:

object(CairoPath)#3 (0) {
}
