This paper discussed the way that sets up the system of deformation correction while making the map digital with scanning, by using point of map margin as reference.

讨论了用扫描法将地图数字化时，以图廓点为参考点建立形变校正系统的问题。

If you print a map and find that one edge of it is "cut off", increase the margin for that edge of the page until the whole map appears.

所以如果你发现打印出的星图有一部分没被打到，请加大页边留白，直到星图能够完全显示为止。
