CairoContext::getCurrentPoint

cairo_get_current_point

(PECL cairo >= 0.1.0)

CairoContext::getCurrentPoint -- cairo_get_current_pointThe getCurrentPoint purpose

Description

Object oriented style

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.

Parameters

context

A valid CairoContext object.

Return Values

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

Examples

Example #1 Object oriented style

<?php

$s 
= new CairoImageSurface(CairoFormat::ARGB32100100);
$c = new CairoContext($s);

$c->moveTo(1010);

var_dump($c->getCurrentPoint());

?>

The above example will output something similar to:

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

Example #2 Procedural style

<?php

$s 
cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE100100);
$c cairo_create($s);

cairo_move_to($c1010);

var_dump(cairo_get_current_point($c));

?>

The above example will output something similar to:

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