x - Horizontal position that the watermark will be in. Positive numbers indicate position from the left and negative numbers indicate position from the right.
y - Vertical position that the watermark will be in. Positive numbers indicate position from the top and negative numbers indicate position from the bottom.
alpha - Watermark image transparency. Should be a number between 0 (fully opaque) and 100 (fully transparent).
