CairoContext::appendPath - Appends a path to current path

       Object oriented style (method):

SYNOPSIS

       public void CairoContext::appendPath (CairoPath	$path)

DESCRIPTION

       Procedural style:
       void cairo_append_path (CairoContext  $context, CairoPath  $path)

	Appends  the  $path  onto  the	current  path.	The  $path  may be either the return value from one of CairoContext::copyPath or CairoCon-
       text::copyPathFlat;

	if $path is not a valid CairoPath instance a CairoException will be thrown

PARAMETERS

	      o $context
		- CairoContext object

	      o $path
		- CairoPath object

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

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

	      $context = new CairoContext($surface);

	      $path = $context->copyPath();

	      $context->appendPath($path);

	      ?>

       Example #2

	      Procedural style

	      <?php

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

	      $context = cairo_create($surface);

	      $path = cairo_copy_path($context);

	      cairo_append_path($context, $path);

	      ?>

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)
	      }
