<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"> Python recipe 580706 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/binary/">binary</a>, <a href="/recipes/tags/conversion/">conversion</a>, <a href="/recipes/tags/decimal/">decimal</a>, <a href="/recipes/tags/hexadecimal/">hexadecimal</a>, <a href="/recipes/tags/octal/">octal</a>, <a href="/recipes/tags/pdfwriter/">pdfwriter</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/utility/">utility</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe shows how to generate a PDF cheat sheet, that contains a table for conversion of the numbers 0 to 255 (the numbers that can fit in one byte) between binary, octal, decimal and hexadecimal representations. The table has four columns, one for each of those bases, and 256 rows, for the numbers 0 to 255.</p> <p>TO use the table, you can look for a number, say in decimal, in the Dec(imal) column (or use the search function of your PDF viewer), then when you find it in some row, just look at the other 3 columns in that row, to find the value of that number in binary, octal and hexadecimal. And use the same procedure if starting with a number in any of the other three bases.</p>

<p style="color: grey"> Text recipe 580701 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/pdfwriter/">pdfwriter</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/pipe/">pipe</a>, <a href="/recipes/tags/pipeline/">pipeline</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe is a command pipeline. The first component of the pipeline is a D language program that makes use of simple functional programming and template / generic programming features of D, to transform some input into the desired output. Both input and output are text. The D program writes the output to standard output, which is then read by a Python program that reads that as input via standard input, and converts it to PDF.</p>

Firebird is a cross-platform, open source RDBMS based on the former Interbase RDBMS from Borland, which they used to bundle with some of their developmemt tools, such as Borland C++ and Borland Delphi.</p> <p>The recipe reads data from a Firebird table, using the fbd Python driver for Firebird, and writes it to PDF, using the xtopdf toolkit.
