>  Looking at the documentation for [{{Graphics.getClip()}}|https://docs.oracle.com/javase/6/docs/api/java/awt/Graphics.html#getClip()], it mentions that the result can be {{null}}, and if {{null}} is passed to the {{Area}} constructor this ends up in a {{NullPointerException}}. Further studying the {{PageDrawer}} code, it seems that {{graphics.getClip()}} shouldn't return {{null}}, however, we proposed a small fix in the following PR that seems to do the trick:
