Looks like a nice tool, thanks. I'm running
scans2pdfon the output ofscantailor-advanced. Some exceptions occurred, so here is the output of running it on the first page. I can provide the image if it would be useful.Note that ubuntu 22.04 has a snap providing
jbig2enc, while you're looking forjbig2.
