cairo_matrix_init_rotate ( float $radians ) : object

Creates 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.
