CairoMatrix::initRotate
cairo_matrix_init_rotate
(PECL cairo >= 0.1.0)
CairoMatrix::initRotate -- cairo_matrix_init_rotate — Creates a new rotated matrix
Description
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
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.
Return Values
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns.
Examples
Example #1 Object oriented style
<?php
/* Create a new Matrix */
$matrix = CairoMatrix::initRotate(0.3);
?>
Example #2 Procedural style
<?php
/* Create a new Matrix */
$matrix = cairo_matrix_init_rotate(0.3);
?>
