PDF is a big complex data format, and several things could have gone wrong, including the file being broken (but in a way that some commercial viewers handle more graceful than what you tried on Linux) and the files using features from newer revisions of PDF than is implemented in those Linux viewers. > Is there another program that would read such a file? There are many PDF viewers in Debian. Probably best way to sift through them is to install the package apt-xapian-index and run these: axi-cache search pdf viewer axi-cache more When your interest is in what PDF files the applications can render, then you need not try them all but can check which underlying PDF rendering library they use which are far more limited. Evince (a.k.a. "documentviewer"), Xpdf, Okular, Atril, Qpdfview and others use Poppler: apt rdepends libpoppler* Gv and others use Ghostscript: apt rdepends libgs9 ghostscript ghostscript-x MuPDF uses its own renderer (developed by same authors as Ghostscript but an independent codebase): apt rdepends qpdf PDF.js is used in some web browsers: apt rdepends pdf.js-common libjs-pdf latexdraw (more a programming tool than a viewer) uses The PDF Renderer. apt rdepends libpdfrenderer-java Calibre and others use PoDoFo: apt rdepends libpodofo* CUPS filters (for printing not a viewer) use QPDF: apt rdepends libqpdf* - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
