IronOCR Library Installation

While the IronOCR Utility provides a visual interactive way to use IronOCR, the IronOCR package offers even more features and languages and an intuitive API for utilizing the customized and optimized Tesseract 5, known as Iron Tesseract. Add Tesseract to your project by using IronOCR and IronTesseract, and you will be able to convert any file or image with text or scanned documents into text and searchable PDFs.

Navigate to the left Filters Panel to queue various filters and see them update in real-time. You can also dequeue or adjust their values:

Applying a Deskew filter here will update the code in the Output panel on the right, enhancing the result's accuracy:

Export Results or Add to .NET Project

To include this result in your own project, use the COPY button in the Code Panel to export the code that replicates the Output Panel results. Paste the code into your IDE and change the filepath to your image filepath.

For scanned documents, if you want a Searchable PDF with text overlayed on the original image or PDF, you can export it using the EXPORT AS PDF button:
