(PECL cairo >= 0.1.0)
CairoMatrix::__construct -- cairo_matrix_init — Creates a new CairoMatrix object
Описание
Объектно-ориентированный стиль (method):
$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:
$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
Возвращаемые значения
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
