"""Génération des bulletins de notes en format PDF
On peut installer plusieurs classes générant des bulletins de formats différents.
La préférence (par semestre) 'bul_pdf_class_name' conserve le nom de la classe Python
utilisée pour générer les bulletins en PDF. Elle doit être une sous-classe de PDFBulletinGenerator
et définir les méthodes fabriquant les éléments PDF:
gen_part_title
gen_table
gen_part_below
gen_signatures
Les éléments PDF sont des objets PLATYPUS de la bibliothèque Reportlab.
Voir la documentation (Reportlab's User Guide), chapitre 5 et suivants.
Pour définir un nouveau type de bulletin:
- créer un fichier source sco_bulletins_pdf_xxxx.py où xxxx est le nom (court) de votre type;
- dans ce fichier, sous-classer PDFBulletinGenerator ou PDFBulletinGeneratorDefault
(s'inspirer de sco_bulletins_pdf_default);
- en fin du fichier sco_bulletins_pdf.py, ajouter la ligne
import sco_bulletins_pdf_xxxx
- votre type sera alors (après redémarrage de ScoDoc) proposé dans le formulaire de paramètrage ScoDoc.
Chaque semestre peut si nécessaire utiliser un type de bulletin différent.
