How to Use System Drawing Images for OCR Processing in C# ByKannapat Udonpant December 30, 2024 Updated June 22, 2025 Share: Unlock the power of IronOCR in C# by watching this tutorial to learn how to effortlessly extract text from images, handle various image loading methods, and optimize OCR on specific regions for enhanced flexibility and precision in your projects! more... In this tutorial, we delve into using IronOCR to extract text from images with System.Drawing in C#. Starting with setting up IronOCR and the necessary namespaces, we guide you through initializing the Tesseract object to read a TIFF image file. By converting this file into a bitmap object, we create an OCR image input instance, allowing IronOCR to process and extract text from the image.The tutorial showcases different methods to handle images, including using Image.FromFile and AnyBitmap from IronSoftware.Drawing, demonstrating the flexibility of IronOCR in processing images loaded through various techniques. Additionally, the video explains how to perform OCR on specific areas of an image by defining a scan region using coordinates and dimensions. By loading this region into an OCR image input method, we extract and print the text to the console.The tutorial concludes with running the project to explore the console output, providing practical insights into extracting text from System.Drawing objects using IronOCR in C#.
