CairoMatrix::initRotate

cairo_matrix_init_rotate

(PECL cairo >= 0.1.0)

CairoMatrix::initRotate -- cairo_matrix_init_rotate — Creates a new rotated matrix

Object oriented style (method):

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

Procedural style:

object cairo_matrix_init_rotate ( float $radians )

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

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