Designing Fonts with Trigonometric Be´Zier Functions

Abstract

Designing and fitting fonts play an important role in computer graphics and are widely used in printing, digital media, animation, and computer systems. This study aims to create accurate font outlines minimizing geometric deviation between the detected and fitted contours. The process includes scanning the font to obtain a digital image, detecting its boundary, finding corner points, dividing the boundary into segments, applying the chord length method for parameterization, identifying break points, and fitting the final outline. Trigonometric Bézier functions are used for fitting because they provide better control over the curves of complex characters than traditional Bézier functions. An algorithm has been developed to automatically fit the outlines of selected Arabic and English characters, showing improved accuracy and smoothness in the results.
