Yann, do you mean you're getting good quality DjVu generated from the PDF? Or from the original scan Jpegs?

Aubrey: when you say directly use the PDF, you mean for the tool to copy that across to Commons and not create a DjVu?

I can have a look at adding that feature perhaps? (Anyone else working on this?)

Hi,

The quality of the result depends of paramaters.
I use Abby FineReader, and I use the high quality possible, which gives good quality DjVu, but of high volume.
It is always a trade-off between quality and volume.

Regards,

Yann

I added this issue to IA-upload tool on github:
Unfortunately, the new PDF > DJVU conversion is useless, as it loses too much quality.
Can we find a solution?
The IA-Upload tool is a great asset for the whole international community,
and it's very simple to teach librarians to upload stuff on IA and then use it to port it on Commons and Wikisource.
But when they upload new stuff on IA, we don't have the IA djvu anymore.
So the tool converts the original PDF to a new DJVU, and this is the part of the process that is failing.
I can think of 2 solutions:
the script creates a good quality djvu
* have a toggle/top-down menu which allow the user to use directly the PDF.
