| $angle | double | Angle by which to rotate the image clockwise. Between 0 and 360. @param mixed $background_color (Optional) The hexadecimal color (like "#FFFFFF" or "#FFF") of the uncovered zone after the rotation. When set to -1 the script will preserve transparency for transparent GIF and PNG images. For non-transparent images the background will be white in this case. Default is -1. @return boolean Returns TRUE on success or FALSE on error. If FALSE is returned, check the {@link error} property to see the error code. |
