I don't understand the exception handling here. multiplyExact and addExact will throw a runtime exception - ArithmeticException. And I don't see where it is caught. The change for ImageLayoutException to extend ArithmeticException doesn't seem like it can help here. Where is the ArithmeticException being turned into ImageLayoutException ?
