CairoContext::clipExtents - Computes the area inside the current clip

       Object oriented style (method):

SYNOPSIS

       public array CairoContext::clipExtents (void  )

DESCRIPTION

       Procedural style:
       array cairo_clip_extents (CairoContext  $context)

	Computes a bounding box in user coordinates covering the area inside the current clip.

PARAMETERS

	      o $context
		- A valid CairoContext object

RETURN VALUES

	An array containing the (float)x1, (float)y1, (float)x2, (float)y2, coordinates covering the area inside the current clip

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

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

	      $context = new CairoContext($surface);

	      var_dump($context->clipExtents());
	      ?>

	      The above example will output something similar to:

	      array(4) {
		[0]=>
		float(0)
		[1]=>
		float(0)
		[2]=>
		float(50)
		[3]=>
		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_extents($context));

	      ?>

	      The above example will output something similar to:

	      array(4) {
		[0]=>
		float(0)
		[1]=>
		float(0)
		[2]=>
		float(50)
		[3]=>
		float(50)

       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:

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

	      Procedural style

	      <?php

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

	      var_dump(cairo_font_extents($con));

	      ?>
