Creates a new rotated matrix
public static void CairoMatrix::initRotate ( float $radians )

Object oriented style (method):

Procedural style:

object cairo_matrix_init_rotate ( float $radians )

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

Parameters:
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.

Returns:

Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.

Examples:
Object oriented style
<?php
/* Create a new Matrix */
$matrix = CairoMatrix::initRotate(0.3);
?>

Procedural style
<?php
/* Create a new Matrix */
$matrix = cairo_matrix_init_rotate(0.3);
