Abstract

Selon la présente invention, une unité 1 de traitement de dessin traite des données de dessin 5 au moyen d'un contenant 4 d'objets de dessin. Le contenant 4 d'objets de dessin est configuré de façon à pouvoir gérer de manière unifiée les mêmes objets de dessin. Lorsque l'unité 1 de traitement de dessin effectue un traitement des données de dessin, une unité de traitement de découpage découpe les objets de dessin qui occupent une région à l'intérieur du contenant 4 d'objets de dessin. Une unité 3 d'exécution de dessin exécute un dessin par disposition du contenant 4 d'objets de dessin qui a été soumis au découpage dans les données de dessin traitées par l'unité 1 de traitement de dessin.
