gd est bien activé sur mon serveur, et avec jpgraph.
J'arrive pas a trouvé le probleme.
Merci.

j'ai les message d'erreur :

Salut,
que vaut $width et $height ?

[andry.aime]

Bonjour,
+1 Thes32
Si $width et $height ont des valeurs, peut être qu'ils sont évalués comme string, dans ce cas, essaie de les caster un int.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$image = ImageCreate((int)$width, (int)$height);
