摘　　要：权值拖曳算法是作者在所设计的多种矢量图文变形方案中较为理想的一种，权值拖曳通过定义若干个拖曳点，拖曳点的移动和待变形点的移动之间存在一定的函数关系，本文对实现方法作了概要介绍，并重点讨论了决定拖曳变形效果的权值函数．Weight-dragging algorithm is the best one of many kinds of deforming strategies of deforming vector graphics and text designed by authors. Weight-dragging is designating points and moving some of them by the purpose of users. There is a functional relationship between the moving of the dragging points and the points to be deformed in the graphics (tests). The implemetation of the method is given in general and the weight-dragging function is discussed.
