Python QR Code Reader API

We can generate and read QR code in Python using Aspose.BarCode for Python. It is a powerful Python QR Code library that allows developers to easily add barcode generation and recognition functionality to their Python applications. It supports a wide variety of barcode formats, including linear and 2D barcodes, and can be used to generate barcodes in various image formats, such as JPEG, PNG, and GIF. The API also provides the ability to recognize barcodes from images and read their data.

Please either download the Python QR Code library package or install the API from PyPI using the following pip command in the console:

pip install aspose-barcode-for-python-via-net 

Read QR Code in Python

We can read QR code in Python with Aspose.BarCode for Python by following the steps given below:

  1. Create an instance of the BarCodeReader class.
  2. Call the read_bar_codes() method and get recognition results.
  3. Finally, loop through the results and show the recognized type and code text.

The following code sample shows how to read a QR code in Python.

Read Incorrect QR Code

We can read corrupt, damaged, low-qualit, and blur QR codes using Aspose.BarCode for Python. For this purpose, we can specify quality settings to detect, recognize and read such QR codes.

We can read evidently incorrect QR code by following the steps given below:

  1. Firstly, create an instance of the BarCodeReader class.
  2. Next, specify the allow_incorrect_barcodes and read_tiny_barcodes quality_settings to True.
  3. After that, call the read_bar_codes() method and get recognition results.
  4. Finally, loop through the results and show the recognized type and code text.

The following code sample shows how to read evidently incorrect QR code in Python.

Recognize Distorted QR Code

We can read distorted or damaged QR code by following the steps mentioned earlier. However, we need to set allow_qr_micro_qr_restoration property to true.

The following code sample shows how to read distorted QR code in Python.

Detecting Colored QR Code on Colored Background

We can also read colored QR code from a colored background image by following the steps mentioned earlier. However, we need to set allow_complex_background property to true.

The following code sample shows how to read colored QR code in Python.
