Python Ctypes for Dynamsoft Barcode Shared Library

An experiment demonstrates how to load and use Dynamsoft Barcode shared libraries by Python Ctypes.

Why Ctypes?

Dynamsoft Barcode Reader for Python is implemented using CPython and has been released to pypi.org:

pip install dbr

The reason behind using Ctypes is to try another way to invoke C APIs in shared libraries in pure Python.

Usage

1. Build the CMake project bridge which is located in the root directory of the project.

   # Windows
   cmake -DCMAKE_GENERATOR_PLATFORM=x64 ..
   cmake --build .
   
   # Linux
   cmake ..
   cmake --build .

2. Get a valid license key from Dynamsoft website and update the line in success.py.

   DBR_InitLicense(instance, c_char_p('LICENSE-KEY'.encode('utf-8')))

3. Run the success.py file.

   python success.py
