Deri -- I was expecting to have to do some work in mom to accommodate PDFPIC, but it turns out I don't. \X'pdf: pdfpic ...' in PDF_IMAGE accepts all the image formats I threw at it--without the need for -U.
PDF_IMAGE still requires the image dimensions for correct placement and scaling, so the only change needed in mom is to the documentation, instructing users to call on pdfinfo(1) for pdf image dimensions and identify(1) for everything else. -- Peter Schaffter https://www.schaffter.ca
