Object oriented style (method):
SYNOPSIS
publicstatic void CairoMatrix::initRotate (float $radians)
DESCRIPTION
Procedural style:
object cairo_matrix_init_rotate (float $radians)
Creats a new matrix to a transformation that rotates by radians provided
PARAMETERS
o $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.
RETURN VALUES
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
