limbus-qrtk

An extremely simplistic QR/DataMatrix/Barcode toolkit for the LImBuS project.

Setup

This project makes use of the dmtx library, so you need to install the headings for it to work.

If you are running a Fedora system, use the following command:

sudo dnf install libdmtx-devel

Now once you have done this, install limbus-qrtk using pip:

pip install git+https://www.github.com/AberystwythSystemsBiology/limbus-qrtk

Usage

There's an example in the examples directory of the repository, but the following is pretty much all you need to get started.

First of all, import the library using the following command:

>>> from limbus_qrtk import DataMatrixReader

Now, we want to load in an image of our DataMatrix array. It should look something like this:

>>> dmr = DataMatrixReader("./path/to/image.jpg")

If you would like to see what the data looks like before exporting, then simply run:

>>> dmr.to_img("./path/to/output.jpg")

This should produce something like:

If you're happy with the results, export it in the format that LImBuS utilises for its barcode functionality.

>>> dmr.to_limbus_json()
