"""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:
|
||
|
