    $angle = deg2rad(40);

    $affineRotate = array(
        "sx" => cos($angle), "sy" => cos($angle), 
        "rx" => sin($angle), "ry" => -sin($angle),

This function is obsolete. Use distortImage() instead, with the affine transformation constant, and an array of six values, sx, rx, ry, sy, tx, ty.

This method has not been properly implemented it seems - it has no effect whatsoever on the image.
