A long value which represents the number of pixel rows added to the top margin.

Note: A value less than 0 indicates that horizontal lines were removed from the top margin making the image smaller. A value greater than 0 indicates that horizontal lines were added to the top margin making the image larger.

When the verticalAddOnly flag is True and the value specified in the property is less than 0, no modification to the top margin of the current image will have occurred. In this case, the value returned by this property represents the adjustment that would have been applied to the top margin if Registration were permitted to remove pixels.

When Registration adds pixels to the image, the added pixels are always White.
