Approach for automatic font outline generation of NüShu
一种女书曲线轮廓字形自动生成方法

For the disadvantages of bitmap font, such as large storage, the quality of zooming was hard to guarantee, this paper designed an approach for auto-generating curve contour character from bitmap. The main idea of the implementation was to extract the contour data of NüShu character, and then proposed an approach for detecting feature points based on maximum error, at last fitted the contour based on straight line and quadratic Bezier curves and stored the data of curves and generated the character of NüShu described by curves. The result shows that this method is very simple and reduces the storage space greatly. The generated curve contour is the same as the original font and it also can eliminate burrs caused by hand-writing. This method is also the basis of computer processing of NüShu characters.
