PDF Text Extraction using fitz / MuPDF (PyMuPDF) (Python)

2016-03-17T12:00:06-07:00

Python recipe 580626 by Jorj X. McKie (cbz, epub, mupdf, openxps, pdf, pymupdf, text_extraction, xps).

Extract all the text of a PDF (or other supported container types) at very high speed. In general, text pieces of a PDF page are not arranged in natural reading order, but in the order they were entered during PDF creation. This script re-arranges text blocks according to their pixel coordinates to achieve a more readable output, i.e. top-down, left-right.

How to parse a table in a PDF document (Python)

Convert JSON to PDF with Python and xtopdf (Python)

2014-12-10T18:02:14-08:00

Python recipe 578979 by Vasudev Ram (json, pdfwriter, sys).

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.

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.

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.

JSON Formatted Logging (Python)

2016-05-27T01:07:42-07:00

Python recipe 580667 by Michael Blan Palmer (json, logging, python).

I have created a package that outputs JSON formatted lines to a log file. It can make use of the standard logging parameters and/or take custom input. The use of JSON in the log file allows for easy filtering and processing.

Configurable JSON Extensions for Python (Python)

2016-05-22T19:00:54-07:00

Python recipe 580664 by Michael Blan Palmer (json, python).

The concept behind the package is to build a single class per type you want to add to json in Python. The new class will have a method for encoding to json and a method for decoding from json. The classes are then loaded into an encoder object and a decoder object that are hooked into the standard json loads and dumps functions.

How to use Python to convert a web page to PDF with a POST request to SelectPdf Online API and save it on the disk (Python)

Validate data easily with JSON Schema (Python)

2015-12-06T21:23:48-08:00

Python recipe 579135 by Vasudev Ram (data, json, jsonschema, python, python2).

This recipe shows how to use the jsonschema Python library, which implements the JSON Schema specification, to easily validate your Python data. It sends good output to stdout and bad output to stderr, for demo purposes.

jsonschema Python library: https://pypi.python.org/pypi/jsonschema

JSON Schema: http://json-schema.org/

dynamically changing encoder (for json) with metaclass (class factory) (Python)

2013-10-24T11:31:44-07:00

Python recipe 578696 by - (class_factory, encode, json, metaclass, metaclasses).

The json.dumps need to be feed with some class (cls =someClass) but what if we want to change the class dynamically? This example can be done by declaring the listOfClasses in class level of course, but the idea is to be changeable. This can be done by the class factory function encoderFacory

Use 'Google Maps Elevation Service' to get elevation data for any location on Earth. (Python)

2012-08-12T20:47:29-07:00

Python recipe 578239 by Aristotelis Stamatiadis (elevation, gis, google_maps).

The Google Maps Elevation Service provides a simple interface for getting elevation data for any location on Earth, including locations under the sea (where the elevation is negative).

The following function is based on the examples presented in the Elevation API web page: https://developers.google.com/maps/documentation/elevation/.

Before using the Elevation Service you must read the rather strict usage limits set by Google in the above web page, especially the term that stipulates that "the Elevation API may only be used in conjunction with displaying results on a Google map; using elevation data without displaying a map for which elevation data was requested is prohibited."

transform command line arguments to args and kwargs for a method call (Python)

2010-03-21T22:41:42-07:00

Python recipe 577122 by Trent Mick (argv, cli, json). Revision 2.

For many of my Python modules I find it convenient to provide a small if __name__ == "__main__": ... block to be able to call individual methods from the command line. This requires some kind of translation of command-line string arguments to args and kwargs for the method call. This recipe uses a few conventions to do that:

the first argument is the method name
positional args are positional (duh)
"key=value" is a keyword argument
an attempt is made to interpret arguments as JSON to allow specifying types other than string
