# cairo_matrix_init

(PECL cairo >= 0.1.0)

CairoMatrix::__construct -- cairo_matrix_initCreates a new CairoMatrix object

### Descrizione

Stile orientato agli oggetti (method):

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 ]]]]]] )

Stile procedurale:

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;

### Elenco dei parametri

`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

### Valori restituiti

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

Example #2 Stile procedurale
