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

AFAIU, Yann is using ABBYY finereader to generate a djvu and then uploads it directly to Commons. So outside of our ia-upload tool.

Ah, okay. So if it could be done in the tool, that'd be nicer.

 

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

Yes.
If the Djvu quality is much lower than the PDF there's no reason to use the djvu over the pdf :-(

Are we saying that we *never* want to use the IA PDF? That if there's a DjVu we use it, and if there isn't we generate our own DjVu from the JP2 and djvu.xml files? Or should the tool user make this call and we give them a drop-down list of "PDF only", "Generate DjVu from PDF", and "Generate DjVu from original scans" with a note about the last of these being higher quality but slower?

I think I'm in favour of just generating a high-quality DjVu and making it simpler for the end user. But we want to be flexible too. jayantanth mentioned that he'd like to be able to just upload the PDF for example.




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


Please ;-)

I can try!  :-)
