CairoMatrix::__construct -- cairo_matrix_init — Creates a new CairoMatrix object
Descrição
Estilo orientado à objeto (method):
$xx = 1.0
[, float $yx = 0.0
[, float $xy = 0.0
[, float $yy = 1.0
[, float $x0 = 0.0
[, float $y0 = 0.0
]]]]]] )Estilo procedural:
$xx = 1.0
[, float $yx = 0.0
[, float $xy = 0.0
[, float $yy = 1.0
[, float $x0 = 0.0
[, float $y0 = 0.0
]]]]]] ) : objectReturns 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;
Parâmetros
-
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
Valor Retornado
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
