Property Value

This property is an array of PointF that contains 4 elements, which spepcifies the difference to the 4 points of the rectangle of watermark.

Everytime you write a watermark, text or photo, it must be containted inside a rectangle. A rectangle has 4 points: left-top, right-top, left-bottom, and right-bottom. What you need to do is set difference for those 4 points in this property. Therefore, setting zero to all of them means no warp occurs.
