Bitmap getWidth() incorrect
Bonjour,
Pour un projet personnel je dois manipuler des images qui sont pour l'instant des images testes.
En les manipulant je passe par l'objet Bitmap. Néanmoins quand je tente d'accéder au propriété de l'image j'ai une largeur qui est différente de la largeur de l'image.
Je dois commettre une erreur mais où?
