Aug 28, 2014 · For this challenge we are investigating how barcodes are produced. Though there are different standards to produce barcodes, they all follow a similar approach based on binary code! Did you know? On a barcode the pattern made using black and white lines is in fact binary code! A black line represents a 1 and a white line a 0. So the following binary code "0101" consists of a thin white line, a ... I'm using the elaphe package for python to generate ean-13 barcode images.
