With bullseye, using a variety of guesses for --infilter (basically permutating words like in the example here): $ lowriter --infilter="Writer Office Open PDF" /tmp/version10.pdf the document does indeed always open in Draw. It shows a poor rendering of the text in sans serif (the original is serif). Sporadic interword spaces are turned into overlaps to make the lines shorter, though they still run over the Draw margins, and even the edge of the paper. Even some short lines have unnecesary overlaps. The document is a mixture of text and music: the drawn items (staves, barlines, notestems, slurs etc) are rendered correctly, but noteheads, rests, clefs, etc., which are in the Emmentaler font, are omitted. I write all this only because I don't know what LO is meant to do under the circumstances, either in its Draw or its Writer manifestation. I've never seen anything I'd describe as "raw pdf", as in: %PDF-1.5 %.... 3 0 obj … I tried opening lowriter with no file, but Insert→Text from File produced an error rather than importing anything from the PDF. Taking the CLI out of the process by File→Open-ing the PDF in Writer, it just opens it in Draw anyway. I don't see any reference to Importing, Filtering or Converting in any of the menus in Writer. BTW I don't think filtering has anything to do with selecting files from the filesystem (as the OP might have implied): the nature of a CLI is that you can filter file-types yourself in a multitude of ways. > > (1) https://bugs.documentfoundation.org/show_bug.cgi?id=141732 > > > > The man page says > >> > >> --infilter="<filter>" > >> Force an input filter type if possible.

For a PDF, I would have thought LO would be able to determine that for itself (see raw text above), but forcing an input filter could be useful to control the process of conversion to, say, text (like pdftotext) or extracting any images (like pdfimages), particularly where it's counter to what would be natural choice (extracting PDF text into Writer, and images into Draw). I do see three files called libpdf{filter,import,ium}lo.so on my system, but I don't know what they're for. (As a LuaTeX/gnumeric/inkscape person, LO is just a viewer for the Microsoft documents I sometimes get sent.) Cheers, David.
