{Arabic typesetting using a Metafont-based dynamic font} {Amine Anane} {Arabic script is a cursive script where the shape and width of letters are not fixed but vary depending on the context and the justification needs. A typesetter must consider those dynamic properties of letters to achieve a high-quality text comparable to Arabic calligraphy. In this talk I will present a parametric font that has been designed as a first step towards such high-quality typesetter. The font is based on Metafont language which can generate a glyph with a given width dynamically and respecting the curvilinear nature of Arabic letters. It uses an extended version of OpenType to support the varying width of the glyphs. I will demonstrate a graphical tool which has been developed specifically to facilitate the design of such dynamic fonts. As a case study, I will compare a handwritten Quranic text with a one generated with this dynamic font and I will conclude by highlighting some future works towards a complete high-quality Arabic typesetter. 2020 update: a demonstration is now online at \url{https://digitalkhatt.org/about}. }
