The primary aim has been to gain a puterised model which closely resembles the original shape and form. The digital form lends itself to be processed by fast processors, and their output to be displayed on graphic devices such as screen displays and laser printers. The benefits of the digital form are also extended to cater for numerically controlled machines. These are employed to produce outlines through cutting or engraving on paper, metal, plastic or wood. When it es to digitling the outlines of characters, additional considerationshave to be included in the modelling, design, phase. The aim of these is to capture the uniqueness and the distinct features of a font, which traditionally were realised by a proficient artisan’s hand and eye. Modern approaches endeavour to gain the same impact by using a set of predefined specifications in the design process. The goal of which is not just to model accurately a desired font, but also to ensure that the displayed version is both legible and aestheticallyacceptable. This paper provides an insight about the design methods used to both model and represent the contours of Latin characters and fonts. It describes the role of the spline as a means of realising the modelling aspect. To this regard, the spline descriptions used by Postscript (BCzier cubic) and TrueType (parabolic) are looked at, and a parativeanalysis made. The discussion throughout is levelled at providing a practical understanding of the subject matter. Introduction The quest for an accurate and aesthetically acceptable representation of outlines of shape has traditionally been undertaken by experienced artisans. They produced desired results by using a skilled hand, having an eye for fine detail and an appreciation of the type and form of the shape itself. This process of generating outlines found popularity in the field of typography, where an exact production and reproduction of contours of characters is required. The task for the typographer was not just to draw a given outline, but also to 外 文翻譯 第 2 頁(yè) capture the distinct features of a particular font type. This manual process of modelling character outlines bees rather tedious and timeconsuming when one realises that there are thousands of Latin font types available, each prisingof at least 100 characters. With the arrival of puters, attempts have been made to automate the design has resulted in software programs under the headings of puteraideddesign (CAD), manufacture (CAM) and geometricdesign (CAGD) being developed. The modem typographer uses a particular design package to capture and model a desired font. The process works with some predefined specifications,ensuring that the modelled image embodiesthe desired font features. In view of modem mercial requirem
