Oops, sorry.
The file built has a djvu extension and a djvu MIME type. It was viewable in EOG. I didn't see it could not be djvu
Sorry for this question. I will look further.
Thanks for this reply
Hello,
Is there a way to build multi-page djvu file from different image pages as it is possible for pdf file ?
"convert *.png document.djvu" only gives a unique-page file with the first image of the set.
My computer is runing Ubuntu 12.10 and ImageMagick 6.7.7-10 2012-08-17 Q16.
Thanks.
