I want to add barcode generation in a Django site and wonder what the best library or api would be. My first preference is something callable from Python - either written in Python or a C/C++ lib that I can wrap with ctypes/SWIG. Otherwise I can call out to the command line if must be.
I need at least EAN and UPC symbologies.
I've tried pybarcode but the image quality is too low. And Elaphe looks promising but from the Python interpreter all I could make was a QR Code -- EAN and UPC errored out (maybe because the syntax/usage was unclear from the documentation).

Use pybarcode and generate the barcode as SVG: http://packages.python.org/pyBarcode/barcode.html#creating-barcodes-as-svg
No problem of image quality in that case.

This thread is quite old, but in case anyone else is looking for an answer to this... code39 is a font, as are most types of barcode. You can simply use google fonts: https://fonts.google.com/specimen/Libre+Barcode+39+Extended+Text?selection.family=Libre+Barcode+39+Extended+Text
Aside from that option, you could host static files, one solution could be this project on github:
https://github.com/Holger-Will/code-39-font
In that project all you need are the files associated with the size you want, and the code39_all.css file. The rest you could delete, if you like.
For your reference, I'm using both here:
{% load staticfiles %}
{% load static %}
<html>
<head>
<link href="https://fonts.googleapis.com/css?family=Libre+Barcode+39+Extended+Text" rel="stylesheet">
<link rel="stylesheet" href="{% static 'code-39-font-master/code39_all.css' %}"/>
</head>
<body>
<style>
body {
font-family: 'Libre Barcode 39 Extended Text', cursive;
font-size: 48px;
}
</style>
<div>I'm just a code39 google font</div>
<div><class="code_39_S">I'm generated with static files!</div>
</body>
