Опис

Об'єктно-орієнтований 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 ]]]]]] )

Процедурний 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;

Параметри

`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

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