# CairoContext::getCurrentPoint

# cairo_get_current_point

(PECL cairo >= 0.1.0)

CairoContext::getCurrentPoint -- cairo_get_current_point — The getCurrentPoint purpose

### 説明

Object oriented style (method):

public array CairoContext::getCurrentPoint ( void )

Procedural style:

array cairo_get_current_point ( CairoContext `$context` )

Gets the current point of the current path, which is conceptually the final point reached by the path so far.

The current point is returned in the user-space coordinate system. If there is no defined current point or if cr is in an error status, x and y will both be set to 0.0. It is possible to check this in advance with CairoContext::hasCurrentPoint.

Most path construction functions alter the current point. See the following for details on how they affect the current point: CairoContext::newPath, CairoContext::newSubPath, CairoContext::appendPath, CairoContext::closePath, CairoContext::moveTo, CairoContext::lineTo, CairoContext::curveTo, CairoContext::relMoveTo, CairoContext::relLineTo, CairoContext::relCurveTo, CairoContext::arc, CairoContext::arcNegative, CairoContext::rectangle, CairoContext::textPath, CairoContext::glyphPath.

Some functions use and alter the current point but do not otherwise change current path: CairoContext::showText.

Some functions unset the current path and as a result, current point: CairoContext::fill, CairoContext::stroke.

### パラメータ

`context`

  A valid CairoContext object.

### 返り値

An array containing the x (index 0) and y (index 1) coordinates of the current point.

### 例

例1 Object oriented style

`<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->moveTo(10, 10);
var_dump($c->getCurrentPoint());
?>`

上の例の出力は、 たとえば以下のようになります。

    array(2) {
      [0]=>
      float(10)
      [1]=>
      float(10)
    }

例2 Procedural style

`<?php
$s = cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE, 100, 100);
$c = cairo_create($s);
cairo_move_to($c, 10, 10);
var_dump(cairo_get_current_point($c));
?>`

上の例の出力は、 たとえば以下のようになります。

    array(2) {
      [0]=>
      float(10)
      [1]=>
      float(10)
    }
