"""Signature des bulletin pdf
XXX en projet, non finalisé: on peut utiliser en attendant les paramétrages des bulletins (malcommodes).
Il ne s'agit pas d'une "signature" électronique, mais simplement d'une image
que l'on intègre dans les documents pdf générés (bulletins, classeur des bulletins,
envois par mail).
La signature est controlée par:
- la présence d'un fichier .../ScoDoc/static/signatures/<DeptId>/<formsemestre_id>/bul_sig_{left|right}
ou, à défaut, .../ScoDoc/signatures/<DeptId>/bul_sig_{left|right}
- les préférences booléennes bul_sig_left et bul_sig_right
(ne pas confondre avec bul_show_sig_left...)
- les préférences bul_sig_left_image_height et bul_sig_right_image_height
(hauteur de l'image, float, en mm)
API:
- form_change_bul_sig( side = "left" | "right", [formsemestre_id])
affiche signature courante, soit globale soit pour le semestre
upload nouvelle
- set_bul_sig( side = "left", [formsemestre_id], image )
Lien sur Scolarite/edit_preferences (sans formsemestre_id)
et sur page "réglages bulletin" (avec formsemestre_id)
