How a font can respect basic rules of Arabic calligraphy

Abstract EN

This paper describes formal bases for designing a PostScript dynamic font respecting some basic rules of Arabic calligraphy.

This font will provide, for instance, a vertical curvilinear characters dynamic stretching that depends on their horizontal stretching according to the Calligraphic rules.

Vertical and horizontal ligatures will also be supported by the proposed font.

The techniques used can be applied in various digital typography contexts such as in typesetting mathematics, to get big delimiters for instance.

The results presented here give both extensions and corrections of some already adopted techniques.
