CairoMatrix::initRotate -- cairo_matrix_init_rotate — Creates a new rotated matrix
Object oriented style (method):
$radians
)Procedural style:
$radians
)Creats a new matrix to a transformation that rotates by radians provided
radiansangle 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.
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);
?>
