<p style="color: grey"> Python recipe 580727 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/conversion/">conversion</a>, <a href="/recipes/tags/files/">files</a>, <a href="/recipes/tags/globbing/">globbing</a>, <a href="/recipes/tags/patterns/">patterns</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pdfwriter/">pdfwriter</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/text_processing/">text_processing</a>, <a href="/recipes/tags/wildcard/">wildcard</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe shows how to convert all text files matching a filename wildcard to PDF, using the xtopdf PDF creation toolkit. For example, if you specify report<em>.txt as the wildcard, all files in the current directory that match report</em>.txt, will be converted to PDF, each in a separate PDF file. The original text files are not changed.</p> <p>Here is a guide to installing and using xtopdf:</p> <p><a href="http://jugad2.blogspot.in/2012/07/guide-to-installing-and-using-xtopdf.html" rel="nofollow">http://jugad2.blogspot.in/2012/07/guide-to-installing-and-using-xtopdf.html</a></p> <p>More details on running the program, and sample output, are available here:</p> <p><a href="http://jugad2.blogspot.in/2016/12/xtopdf-wildcard-text-files-to-pdf-with.html" rel="nofollow">http://jugad2.blogspot.in/2016/12/xtopdf-wildcard-text-files-to-pdf-with.html</a></p>
