![]() ![]() ![]() provides us with a directed graph of allographicĬlasses. We use this structure toĮnhance the text model and obtain better results in standard NLP operations.įirst of all, to tackle the problem of graphical variation we defineĪllographic classes of characters. They can then use the design fea-tures embedded into these struc-ture elements (stem width, behavior of curved parts, contrast between thick and thin shape parts, and so on) to design the font's remaining characters., Today's industrial font description standards such as Adobe Type 1 or TrueType represent typographic characters by their shape outlines, because of the simplicity of digitiz-ing the contours of well-designed, large-size master characters., How-ever, outline characters only implic-itly incorporate the designer'sĬhinese characters have a complex and hierarchical graphical structureĬarrying both semantic and phonetic information. To create a new typeface family, type designers gen-erally start by designing a few key characters, such as o, h, p, and v, incorporating the most important structure elements such as vertical stems, round parts, diagonal bars, arches, and serifs (see Figure 1). Design tradition, the rules related to visual appearance, and the design ideas of a skilled character designer., The typographic design process is structured and sys-tematic: letterforms are visually related in weight, con-trast, space, alignment, and style.
