설명

객체 기반 형식 (method):

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

절차식 형식:

object cairo_matrix_init_rotate ( float $radians )

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

인수

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.

반환값

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