CairoMatrix::initRotate -- cairo_matrix_init_rotateCreates a new rotated matrix


Stile orientato agli oggetti (method):

public static CairoMatrix::initRotate ( float $radians ) : void

Stile procedurale:

cairo_matrix_init_rotate ( float $radians ) : object

Creates a new matrix to a transformation that rotates by radians provided

Elenco dei parametri


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.


Example #1 Stile orientato agli oggetti

/* Create a new Matrix */
$matrix CairoMatrix::initRotate(0.3);

Example #2 Stile procedurale

/* Create a new Matrix */
