In this tutorial, we delve into the process of reading barcodes and QR codes from PDF documents using Iron OCR in C. The tutorial begins with the installation of Iron OCR in the project using a package manager. We then proceed to import Iron OCR and set up the necessary configurations, including the license key, to unlock the library's full features. The tutorial explains how to initialize the Iron Tesseract OCR engine and configure it to read barcodes using the OCR PDF input class. By loading a PDF document containing barcodes, the OCR extracts and prints the barcode data in the console. Similarly, the tutorial covers the extraction of QR codes from another PDF document. The step-by-step guide illustrates how Iron OCR simplifies the integration of barcode and QR code reading functionalities into C applications. The tutorial concludes by encouraging developers to explore the capabilities of Iron OCR by signing up for a trial and downloading the package. This resource is ideal for developers seeking to enhance their applications with robust code reading features.
