This paper presents a practical method of Chinese fonts composition which uses uniform cubic B-spline interpolating curves to express Chinese stroke out line. It builds correspondence relationship between composited curves based on continuity and uniqueness of B-spline interpolating curve. If compositin ratio coeff. and unified control point's length of B-spline curves and range of their parametic values are given

new fonts are generated by new stroke out line expression. Simulation results show it is a simple

easy and effentive method of font composition.
