Subject: Adaptation suite au remaniement du code des images. Ajout de
 l'attribut -composealpha. Mise en correspondance des types d'attributs avec
 la doc. Adaptation des prototypes de ToArea et Pick pour accomoder les
 nouvelles fonctionalit�s des commandes de find/addtag. Suppression de la
 variable de classe has_fields
