Python Barcode Reader

Barcodes are machine-readable representations of data visually represented by parallel lines or geometric patterns. They provide a quick and accurate way to store and retrieve information, such as product details, inventory codes, or tracking numbers. Barcodes come in various types, including UPC, EAN, QR codes, and more. Each type has a specific structure and encoding mechanism. In this blog post, we will learn how to build a high-performance Python barcode reader. A Python tutorial accompanied by code examples will show you how to scan barcodes.

Python Barcode Reader API

We will use Aspose.BarCode for Python for scanning and reading barcodes. It is a barcode generation and recognition library that allows you to add barcode functionalities to your Python applications. It provides a simple and intuitive API to generate and recognize various types of barcodes, including QR codes, Code 128, EAN-13, UPC-A, and more. With Aspose.BarCode for Python, you can easily generate barcode images, customize their appearance, and read barcodes from images or scanned documents. It is a powerful tool for integrating barcode capabilities into Python projects.

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

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

Python Read Barcode from Image

We can scan and read a barcode by following the steps below:

  1. Create an instance of the BarCodeReader class with an image path as an argument.
  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 Barcode from an image in Python.

Read Multiple Barcodes in Python

Similarly, we scan and read multiple barcodes available in the document by following the steps mentioned earlier.

The following code sample shows how to read multiple Barcodes from an image in Python.

Read Specific Barcode Type in Python

We can scan and read a specified barcode type by following the steps below:

  1. Create an instance of the BarCodeReader class.
  2. Specify image path and Barcode DecodeType as argument.
  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 scan and read a specific barcode type in Python.

Python Barcode Scanner – Specify Quality Settings

We can specify various quality settings to read distorted, damaged, or low-quality barcode images by following the steps below:

  1. Create an instance of the BarCodeReader class with image path as an argument.
  2. Specify various quality settings using the quality_settings class.
  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 specify quality settings for Python barcode scanner.
