# Fonctions
Plein de fonctions qu'il serait bon de documenter :)
## Contours
Détecter des contours est une activité respectable.
## Exporter
Une méta-fonction qui va sauvegarder (dans la mesure de ses conséquences)
une image en fonction de l'extension du nom de fichier.
## Sfx
Effets spéciaux divers.
## Dithering
Work in progress...
