一种快速有效的矢量汉字转换为点阵的方法

A Method for Converting Vector Words into Matrix Words Rapidly and Effectively

由于矢量汉字是以字的图形坐标为基础，因而矢量汉字占用存储空间少，非常容易实现按任意比例进行缩放与按任意角度进行旋转，且缩放与旋转后文字边缘不会出现锯齿，但矢量汉字必须在相应的缩放与旋转后转换为对应的字的点阵方可显示其实心汉字。本文提出一种快速有效的矢量汉字转换为相应点阵的方法。该方法利用封闭区域的边缘链码作为启发性知识来实现汉字的填充，从而将矢量汉字快速地转换为点阵。

As vector Chinese words are based on graphic coordinates, so they take up less memory and they are easily magnified and rotated. Moreovere, the words have no zigzag edges after transformed.However, the vector Chinese words only give the outline of words, they have to be converted into matrix words according to their graphic coordinates. This paper presents a method for converting vector words into matrix words by using edge chain codes as heuristic knowledge to fill the words, thus makes the vector words converted into matrix words rapidly and effectively.
