unable to open file `test.png'Mais il ne montre rien d'évident. Et il semble que ce journal de débogage se comporte de manière complètement différente que sans -debug car l'erreur originale n'existe pas. Voir le journal complet .
Il y a un problème similaire à http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=22466 mais je ne comprends pas bien quelle est la solution.
