Since Q1 2025 the RadPdfProcessing library supports Optical Character Recognition (OCR). OCR is the electronic or mechanical conversion of images of typed, handwritten, or printed text into machine-encoded text from a scanned document.

This project demonstrates how to use [TesseractOcrProvider](https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/formats-and-conversion/ocr/ocrformatprovider) that allows you to import an image to get a RadFixedPage.

8+
1. Download the DPL assemblies ( .NEt Framework 4.6.2) from your Telerik account: [Download Product Files](https://docs.telerik.com/devtools/document-processing/getting-started/download-product-files).
9+
10+
2. Paste the following assemblies in the **AssemblyReferences** folder:
11+
12+
* Telerik.Windows.Documents.Core.dll
13+
* Telerik.Windows.Documents.Fixed.dll
14+
* Telerik.Windows.Documents.Fixed.FormatProviders.Ocr.dll
15+
* Telerik.Windows.Documents.TesseractOcr.dll
16+
* Telerik.Windows.Zip.dll
17+
18+
3. Build the project and run it.
