Bonjour,
Je fais un b�te drawImage, et une obscure classe de sun.awt me renvoit un
NullPointerException. J'ai pas trouv� cette classe dans les sources de java.
Voici la fin du stack trace :
java.lang.NullPointerException

Que se passe-t-il docteur ?
Mon code qui d�clenche l'exception :
Image image = bufImage.getScaledInstance(w, -1, Image.SCALE_SMOOTH);
graphics.drawImage(image, 0, 0, this); // -> NullPointerException
