I'm playing with djvu files, luckily I found a "simple" way to build a GUI and so I'm using a self-build djvu text editor with some features that allow many developments (select and save cropped images from page images; saving to ws nsPage text by pywikibot; aligning djvu text layer with ws nsPage text). Please don't ask me to put the scripts into Git or Github since I simply can't do this.... it's a blame but I can't. Here a draft doc about what I'm doing: https://it.wikisource.org/wiki/Utente:Alex_brollo/Djvu_Editor_-_Documentazi… ; it's in Italian, but I found that Chrome translator from Italian into English does a surplisingly good translation. Obviously I'll be happy to share the code with any of you; consider that I'm a DIY "programmer", and that therefore to read my code for a good programmer would be a terrible pain. Alex
