Barcode Reader

This is a simple Python application that allows you to decode barcodes from image files using the pyzbar library and display the decoded data in a graphical user interface (GUI) built with the tkinter library.

Prerequisites

Before you can run this application, you need to have the following libraries installed:

• pyzbar: A Python wrapper for the ZBar barcode library, which provides functions to decode barcodes from image files.
• opencv-python: A Python wrapper for the OpenCV computer vision library, which provides functions to read and manipulate image files.
• Pillow: A Python imaging library that provides functions to resize and display images.

+You can install these libraries using pip, the package installer for Python. Open a terminal or command prompt and run the following commands:

pip install pyzbar
pip install opencv-python
pip install Pillow
