Creates a new CairoMatrix object - Справочник: PHP5.4

Описание

Объектно-ориентированный стиль (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 ]]]]]] )

Процедурный стиль:

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;

Список параметров

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
