Zbar

Scan one or more barcodes from a JPEG image.

The API for this library is very simple:

iex>File.read!("QR_REF1.jpg")|>Zbar.scan()%Zbar.Symbol{data: "REF1",points: [{40,40},{40,250},{250,250},{250,40}],quality: 1,type: "QR-Code"}

More detailed API documentation can be found at https://hexdocs.pm/zbar.

Installation

This package is available in Hex and can be installed by adding :zbar to your list of dependencies in mix.exs:

defdepsdo[{:zbar,"~> 0.2"}]end

You will also need to have zbar and libjpeg installed in order to compile the required native code. On OSX with Homebrew, this is as simple as:

$ brew install zbar libjpeg
