CairoContext::getCurrentPoint - The getCurrentPoint purpose

       Object oriented style

SYNOPSIS
       public array CairoContext::getCurrentPoint (void  )

DESCRIPTION
       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:  CairoCon-
       text::newPath,  CairoContext::newSubPath,  CairoContext::appendPath,  CairoContext::closePath,  CairoContext::moveTo, CairoContext::lineTo,
       CairoContext::curveTo, CairoContext::relMoveTo, CairoContext::relLineTo, CairoContext::relCurveTo, CairoContext::arc, CairoContext::arcNeg-
       ative, 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
	      o $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::ARGB32, 100, 100);
	      $c = new CairoContext($s);

	      $c->moveTo(10, 10);

	      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_IMAGE, 100, 100);
	      $c = cairo_create($s);

	      cairo_move_to($c, 10, 10);

	      var_dump(cairo_get_current_point($c));

	      ?>

	      The above example will output something similar to:

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