Hi Gunnar,
Hmmm... But please do take note that I _did_ have mupdf-tools installed when Impressive failed to analyze the PDF document.
Did you though? Impressive detected "Poppler/Xpdf" as the renderer, which is an indicator of the absence of mupdf-tools. If you can confirm that "mutool -v" works on your system (in the sense of: prints a version number instead of a "command not found" message), I'd have some homework to do though ;)
mupdf-tools is already a hard dependency:$ apt show impressive|egrep '^(Recom|Dep|Sug)' Depends: python3, python3-pygame, python3-pil, mupdf-tools (>= 1.5) | poppler-utils
Unfortunately, it's not (yet?) a hard dependency -- mutool (from mupdf-tools) *or* pdftoppm (from poppler-utils) is. If you had installed poppler-utils previously and install Impressive, the way the dependencies are currently set up, apt won't pull in mupdf-tools because the dependency is already satisfied by poppler-utils. Best regards, Martin Fiedler
