patch_render_engine_c3.py — Chantier C3 (Moteur durci)
|
|
======================================================
|
|
Patch strict de render_engine_v2.py :
|
|
P1. Import optionnel de measure.py (mesure PIL réelle).
|
|
P2. estimate_text_height() délègue à la mesure réelle quand elle est
|
|
disponible (fallback : heuristique v2 inchangée) + ajoute
|
|
strip_markdown_tree() (nettoyage récursif du Markdown résiduel).
|
|
P3. Fitter anti-débordement dans _text() : si le texte mesuré dépasse
|
|
la zone, réduction par pas de 1 pt (plancher 60 % du nominal) puis
|
|
troncature avec « … » — chaque ajustement est tracé en console.
|
|
Désactivable par appel (fit=False) ou globalement (FIT_TEXT=0).
|
|
P4. Nettoyage Markdown appliqué à TOUTE donnée entrante de render().
|
|
P5. Speaker notes : champ notes: par slide → zone notes PowerPoint.
|
|
|
|
Usage (dossier du pipeline, single-line) :
|
|
python3 patch_render_engine_c3.py
|
|
Prérequis : measure.py à côté (sinon P1/P3 restent inertes, sans casse).
|
|
Vérifie chaque ancre, écrit render_engine_v2.py.bak-c3, compile,
|
|
idempotent.
