Port of ZXing DataMatrix decode only
npm install datamatrix-decode
A port of the DataMatrix 2D barcode decoding capability from ZXing to javascript. Uses some code from Lazar Laszlo's jsqrcode.
This module does not include any of the detection / image recognition functionality. This module is what you use to extract the encoded data from a DataMatrix 2D barcode once you know the (boolean) value of each square/element in a barcode.
Currently only supports ASCII encoded data and numeric (digit pairs).
