Ascii art to SVG

Jeudi 1 octobre 2009

L’objectif avoué de cet article est de fournir dans une première phase une ébauche d’un script permettant :

  • de traiter en entrée un fichier de type ascii
  • de fournir en sortie un fichier SVG

Dans une seconde partie ce code devra être réécrit en langage C et s’intégrer au projet jp2a.
