How to Use Input Images for OCR Processing in C# ByKannapat Udonpant January 30, 2025 Updated June 22, 2025 Share: Unlock the full potential of your C# projects by watching this tutorial, where you'll master OCR techniques with IronOCR to efficiently extract text from images, byte arrays, and specific regions, enhancing your application's text recognition capabilities! more... In this video tutorial, viewers learn how to perform Optical Character Recognition (OCR) in C# using the IronOCR library. The tutorial begins by setting up the necessary environment, including installing the IronOCR package and setting the license key. It guides users through the process of importing required namespaces and instantiating an IronTesseract object, which is crucial for performing OCR on images.The tutorial demonstrates how to read text from an image file named 'label.png' by using an OCR image input class. It explains the read method, which processes the image and extracts text, subsequently printing it to the console.The tutorial also shows how to handle images stored as byte arrays, which is useful when images are sourced from streams or other non-file inputs. It further discusses performing OCR on a specific region of an image by defining the area with coordinates and dimensions, enabling selective text extraction. The video concludes with a demonstration of the tutorial's examples, showing outputs of extracted text from full images, byte arrays, and specified regions. Viewers are encouraged to integrate these techniques into their projects to enhance OCR capabilities. The tutorial ends with a call to action, inviting viewers to download the IronOCR package and explore its features.Further Reading: How to Read from Streams show less
