CairoMatrix::__construct

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.
