CairoContext::clipRectangleList - Retrieves the current clip as a list of rectangles

       Object oriented style (method):

SYNOPSIS

       public array CairoContext::clipRectangleList (void  )

DESCRIPTION

       Procedural style:
       array cairo_clip_rectangle_list (CairoContext  $context)

	Returns a list-type array with the current clip region as a list of rectangles in user coordinates

PARAMETERS

	      o $context
		- A valid CairoContext object created with CairoContext::__construct or cairo_create(3)

RETURN VALUES

	An array of user-space represented rectangles for the current clip

	(The  status  in  the  list may be CAIRO_STATUS_CLIP_NOT_REPRESENTABLE to indicate that the clip region cannot be represented as a list of
       user-space rectangles. The status may have other values to indicate other errors.)

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

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

	      $context = new CairoContext($surface);

	      var_dump($context->clipRectangleList());

	      ?>

	      The above example will output something similar to:

	      array(1) {
		[0]=>
		array(4) {
		  ["x"]=>
		  float(0)
		  ["y"]=>
		  float(0)
		  ["width"]=>
		  float(50)
		  ["height"]=>
		  float(50)
		}
	      }

       Example #2

	      Procedural style

	      <?php

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

	      $context = cairo_create($surface);

	      var_dump(cairo_clip_rectangle_list($context));

	      ?>

	      The above example will output something similar to:

	      array(1) {
		[0]=>
		array(4) {
		  ["x"]=>
		  float(0)
		  ["y"]=>
		  float(0)
		  ["width"]=>
		  float(50)
		  ["height"]=>
		  float(50)
		}
	      }

CairoContext::curveTo - Adds a curve

       Object oriented style (method):

SYNOPSIS

       public void CairoContext::curveTo (float  $x1, float  $y1, float  $x2, float  $y2, float  $x3, float  $y3)

DESCRIPTION

       Procedural style:
       void cairo_curve_to (CairoContext  $context, float  $x1, float  $y1, float  $x2, float  $y2, float  $x3, float  $y3)

	Adds  a cubic Bezier spline to the path from the current point to position $x3 ,$y3 in user-space coordinates, using $x1, $y1 and $x2, $y2
       as the control points. After this call the current point will be $x3, $y3.

	If there is no current point before the call to CairoContext::curveTo this function will behave as if preceded	by  a  call  to  CairoCon-
       text::moveTo ($x1, $y1).

PARAMETERS

	      o $context
		- A valid CairoContext object created with CairoContext::__construct or cairo_create(3)

	      o $x1
		- First control point in the x axis for the curve

	      o $y1
		- First control point in the y axis for the curve

	      o $x2
		- Second control point in x axis for the curve

	      o $y2
		- Second control point in y axis for the curve

	      o $x3
		- Final point in the x axis for the curve

	      o $y3
		- Final point in the y axis for the curve

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
	      $c = new CairoContext($s);

	      $c->setSourceRgb(0, 0, 0);

	      $c->paint();

	      $c->moveTo(10, 50);
	      $c->setLineWidth(5);
	      $c->setSourceRgb(.1, 0, 1);
	      $c->curveTo(20, 80, 80, 20, 90, 50);
	      $c->stroke();

	      $s->writeToPng(dirname(__FILE__) . '/curveTo.png');
	      ?>

       Example #2

	      Procedural style

	      <?php

	      $s = cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE, 100, 100);
	      $c = cairo_create($s);

	      cairo_set_source_rgb($c, 0, 0, 0);

	      cairo_paint($c);

	      cairo_move_to($c, 10, 50);
	      cairo_set_line_width($c, 5);
	      cairo_set_source_rgb($c, .1, 0, 1);
	      cairo_curve_to($c, 20, 80, 80, 20, 90, 50);
	      cairo_stroke($c);

	      cairo_surface_write_to_png($s, dirname(__FILE__) . '/curve_to.png');
