CairoMatrix::__construct -- cairo_matrix_init — Creates a new CairoMatrix object
Опис
Об'єктно-орієнтований 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
]]]]]] )Процедурний 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;
