In this tutorial, we explore the process of extracting text from images using IronOCR, a powerful library for C#. The session begins with setting up a C# console application in Visual Studio and installing the IronOCR library via the NuGet Package Manager.Once the library is imported, an IronTesseract object is initialized, and its configuration options are fine-tuned to enable barcode reading and set the language to English. This setup allows for accurate text recognition and enhanced performance through multi-threading. Additional features include rendering PDFs and setting page segmentation mode to Auto OSD, which automatically segments and divides lines with words.The tutorial further explains how to use configuration variables for behavior fine-tuning, such as enabling parallelization for smooth execution and recognizing table layouts. Text inversion is disabled to improve results. The tutorial provides a link for more configuration options.Next, an image file is loaded using the OCR input object, and the IronOCR is used to extract text from the image. The recognized text is output to the console, demonstrating the library's high accuracy.The tutorial concludes by highlighting IronOCR as a powerful tool for extracting text from images and PDFs, encouraging viewers to try it with a provided trial link.
