Question unreadable pdf and strange behaviour(e-ink leaking ?!)

Bonjour.

J'ai réalisé que ma liseuse est incapable de lire une bonne partie des documents scannés de archive.org.
Le fichier est gros mais se lit sans problème sur l'ordinateur, mais sur la liseuse l'affichage est tout noir et l'encre éléctronique semble avoir coulé ! Je ne comprend pas. Que quelqu'un essaie et voie à quoi ça ressemble. J'ai coupé le fichiers en petits morceaux, rien n'y fait. https://ia800306.us.archive.org/23/i...q00hall_bw.pdf

Merci
firmware numéro 5.6.5

C'est parce que c'est un "scan," un jpg ou une image insère dans un pdf. Tu peux essayer de changer le contraste dans ton e-reader, si le "setting" existe.

On peut essayer de faire un "OCR" du PDF original, mais ça sera difficile aux causes de tous les caractères mathématiques.

On peut aussie extraire les images du PDF et utiliser un logiciel comme Photoshop pour changer le contraste, mais c'est beaucoup de travail, et les résultats ne seront pas forcément efficaces.
