CairoMatrix::initRotate -- cairo_matrix_init_rotate — Creates a new rotated matrix
Descrizione
Stile orientato agli oggetti (method):
public static void CairoMatrix::initRotate
( float
$radians
)Stile procedurale:
object cairo_matrix_init_rotate
( float
$radians
)Creats a new matrix to a transformation that rotates by radians provided
Elenco dei parametri
-
radians -
angle of rotation, in radians. The direction of rotation is defined such that positive angles rotate in the direction from the positive X axis toward the positive Y axis. With the default axis orientation of cairo, positive angles rotate in a clockwise direction.
Valori restituiti
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
