2、aracter outlines becomes rather tedious and time-consuming when one realises that there are thousands of Latin font types available, each comprisingof at least 100 characters.With the arrival of computers, attempts have

3、been made to automate the design process.This has resulted in software programs under the headings of computer-aided-design (CAD), manufacture (CAM) and geometric-design (CAGD) being developed. The modem typographer uses

4、 a particular design package to capture and model a desired font. The process works with some pre-defined specifications,ensuring that the modelled image embodiesthe desired font features.In view of modem commercial requ

5、irements for a fast and accurate means of computerising a given outline, most design systems make use of a mathematical description. This has the attraction, when compared to the manual approach, of providing a mo

6、delled image at a faster rate and yielding within, and between, design systems. In addition, the resulting image is in a form which can be transformed (translated, rotated, scaled Ftc) without distortion by using a s

7、imple and an appropriated matrix.The simplest mathematical description makes use of straight line segments from point to point around the outline. An example of the approach is depicted in Fig 1. Clearly, it can be seen

8、 that the resulting model gives a coarse representation of the original. More data points and thus line segments will be required to yield the desired outcome. Even then, it is not certain whether the resulting represen
