Many-knot spline interpolating curves are suitable to computer aided geometric design anddata points interpolation. In this paped, the properties of many-knot spline interpolating curves arediscussed and their applications in font design are considered. The differences between many-knotspline interpolating curves and the curves genoaed by exceeding-lacking adjuStment algorithm aregiven.展开更多

This paper describes the work of adding a Chinese ThueType font ren- derer under X's font support mechanism. First, the origin of the idea is introduced, followed by a brief study of ThueType font and its rasterization algorithm, then the font support mechanism in X Window is discussed.
