(PECL cairo >= 0.1.0)

CairoMatrix::__construct -- cairo_matrix_init — Creates a new CairoMatrix object

### Beschreibung

Object oriented style (method):

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 ]]]]]] )

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;

### Parameter-Liste

`xx`

  xx component of the affine transformation

`yx`

  yx component of the affine transformation

`xy`

  xy component of the affine transformation

`yy`

  yy component of the affine transformation

`x0`

  X translation component of the affine transformation

`y0`

  Y translation component of the affine transformation

### Rückgabewerte

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

### Beispiele

Beispiel #2 Procedural style

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