CairoContext::fontExtents - Get the font extents

       Object oriented style (method):

SYNOPSIS

       public array CairoContext::fontExtents (void  )

DESCRIPTION

       Procedural style:
       array cairo_font_extents (CairoContext  $context)

	Gets the font extents for the currently selected font.

PARAMETERS

	      o $context
		- Description...

RETURN VALUES

	An array containing the font extents for the current font.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

	      $sur = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
	      $con = new CairoContext($sur);

	      var_dump($con->fontExtents());

	      ?>

	      The above example will output something similar to:

	      array(5) {
		["ascent"]=>
		float(10)
		["descent"]=>
		float(3)
		["height"]=>
		float(13.3125)
		["max_x_advance"]=>
		float(26.65625)
		["max_y_advance"]=>
		float(0)
	      }

       Example #2

	      Procedural style

	      <?php

	      $sur = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
	      $con = cairo_create($sur);

	      var_dump(cairo_font_extents($con));

	      ?>

	      The above example will output something similar to:

	      array(5) {
		["ascent"]=>
		float(10)
		["descent"]=>
		float(3)
		["height"]=>
		float(13.3125)

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)
