CairoMatrix::__construct - Creates a new CairoMatrix object

       Object oriented style (method):

SYNOPSIS

       public CairoMatrix::__construct ([float	$xx = 1.0], [float  $yx = 0.0], [float	$xy = 0.0], [float  $yy = 1.0], [float	$x0 = 0.0], [float
       $y0 = 0.0])

DESCRIPTION

       Procedural style:
       object cairo_matrix_init ([float  $xx = 1.0], [float  $yx = 0.0], [float  $xy = 0.0], [float  $yy = 1.0], [float  $x0 = 0.0], [float  $y0 =
       0.0])

	Returns  new  CairoMatrix object. Matrices are used throughout cairo to convert between different coordinate spaces. Sets matrix to be the
       affine transformation given by xx, yx, xy, yy, x0, y0. The transformation is given by: x_new = xx * x + xy * y + x0; and y_new = yx *  x  +
       yy * y + y0;

PARAMETERS

	      o $xx
		- xx component of the affine transformation

	      o $yx
		- yx component of the affine transformation

	      o $xy
		- xy component of the affine transformation

	      o $yy
		- yy component of the affine transformation

	      o $x0
		- X translation component of the affine transformation

	      o $y0
		- Y translation component of the affine transformation

RETURN VALUES

	Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Create a new Matrix */
	      $matrix = new CairoMatrix(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Create a new Matrix */
	      $matrix = cairo_matrix_init(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
	      ?>

CAIRO_CLIP_EXTENTS(3)							 1						     CAIRO_CLIP_EXTENTS(3)

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)
	      }
