This tutorial provides a comprehensive guide on using Tesseract in conjunction with IronOCR to recognize text in multiple languages from PDFs and images. First, ensure that IronOCR and the necessary language packs are installed in your project using the NuGet package manager. Begin by importing the required namespaces and setting up IronOCR with a valid license key to unlock its full capabilities. Instantiate the IronTesseract object to perform optical character recognition, initially using English as the default language. To add support for additional languages, such as Russian, utilize the method to add a secondary language.
