<p style="color: grey"> Python recipe 578979 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/json/">json</a>, <a href="/recipes/tags/pdfwriter/">pdfwriter</a>, <a href="/recipes/tags/sys/">sys</a>). </p> <p>This recipe show the basic steps needed to convert JSON input to PDF output, using Python and xtopdf, a PDF creation toolkit. xtopdf is itself written in Pytho, and uses the ReportLab toolkit internally.</p> <p>We set up some needed values, such as the output PDF file name, the font name and size, the header and footer, and the input lines for the body of the PDF output; all these values are passed in JSON format (in a single dictionary) to a function that uses those values to generate a PDF file with the desired content.</p> <p>The code is intentionally kept simple so as to require the least amount of code needed to demonstrate the techniques involved. But it can be generalized or extended to more complex situations.</p>

<p style="color: grey"> Batch recipe 579142 by <a href="/recipes/users/4173351/">Vasudev Ram</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/processes/">processes</a>, <a href="/recipes/tags/process_management/">process_management</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/windows/">windows</a>). </p> <p>This recipe shows how you can generate a Windows process list or task list (basically, a list of running processes, with some information about each of them), to a PDF file, using the Windows TASKLIST command along with the xtopdf toolkit. The list is sorted in ascending order of memory usage of the processes, before writing it to PDF.</p> <p>It differs somewhat from other xtopdf recipes, in that no additional code needs to be written, over and above what is already in the xtopdf package. We just have to use the needed commands there, in a series of commands or a pipeline.</p> <p>However, one can still write additional code, by modifying the program used (StdinToPDF.py), if needed, to customize the PDF output.</p>

<p style="color: grey"> Python recipe 579146 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/pipe/">pipe</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/python2/">python2</a>, <a href="/recipes/tags/unix/">unix</a>). </p> <p>This recipe shows how to create a Unix pipeline that generates PDF output, under the control of a Python program. It is tested on Linux. It uses nl, a standard Linux command that adds line numbers to its input, and selpg, a custom Linux command-line utility, that selects only specified pages from its input, together in a pipeline (nl | selpg). The Python program sets up and starts that pipeline running, and then reads input from it and generates PDF output.</p>
