Creación de Thumbnails

[txakin]

Hola a todos,

Quiero integrar en mi Alfresco, el proyecto de forge para la creación de thumbnails.

Para ello me he instalado el ImageMagick-6.4.5-Q16 y luego he seguido los pasos del README que hay en el proyecto.

En mi Alfresco, me he creado una regla, para la creación de contenidos, para que siempre me genere el thumbnail del documento que vaya a subir (PDF practicamente el 100%), y siempre me da un error :

Alguien sabe por qué puede ser este error o me puede guiar paso a paso?

Un saludo y muchas gracias por la ayuda

Hola txakin,
La verdad que no sé porqué motivo te da ese error.

Rebuscando un poco encontré este post dentro de la comunidad inglesa: http://forums.alfresco.com/en/viewtopic.php?f=7&t=11377
En ese caso la transformación no es de pdf a imagen…pero bueno, quizás te da alguna idea (qui´zas sea algún tema de versiones o algo similar).

Saludos!
