Fonctionnement des ratios d’extension

  • Chaque ratio est mesuré par rapport à la largeur ou à la hauteur d’origine
  • La zone de canvas étendue combinée doit toujours rester dans les limites de surface documentées par Kling
  • Commencez par de petites valeurs comme 0.1 de chaque côté avant de tenter des extensions plus importantes
