Sur le forum de la communauté Imagemagick, on trouve des messages récurrents sur les problèmes de mémoire, par exemple ici :
C'est décrit aussi sur le site, ici :

Même en monochrome ou gris, il semblerait que les images sont mises en mémoire avec 4 canaux et sur 16 bits ! Mes images occuperaient donc chacune environ 70 Mb en mémoire !!

J'ai une solution acceptable via le traitement de lots d'une cinquantaine d'images et l'importation successive de plusieurs fichiers tif dans le logiciel de traitement en aval.

N'empêche que c'est pas très satisfaisant et que ce devrait être possible de générer des fichiers tif monochrome en utilisant beaucoup moins de mémoire. Un fichier final d'une centaine de page fait à peine 10 Mb !
