Powerful Royalty Free OCR SDK for .NET

High performance, royalty-free C# .NET OCR recognition on Windows 32bit and 64bit.

OCR SDK for .NET is an OCR library that allows developers to easily embed high-quality optical character recognition functionality in their products. OCR SDK for .NET is a 100% royalty-free SDK library for developers. As a result, our customers can enjoy the lowest total cost of ownership of a quality OCR system, which enables them to create more-competitive software products.

OCR SDK for .NET offers a high performance API library for you to equip your C# .NET applications (Windows applications, Sliverlight, ASP.NET web service applications, ActiveX controls, etc.) with functionality of extracting text and position information from scanned documents.

You can convert images (in various formats like JPEG, PNG, TIFF, PDF, etc.) into editable document formats (Text, Word, Excel, RTF, HTML, XML, searchable PDF, etc.). With this product, you can easily implement full document management solutions.

OCR SDK for .NET example in C# source code,

System.Type OCRType = System.Type.GetTypeFromProgID("VeryPDF.ocr2anyCom");
VeryPDF.ocr2anyCom OCRCom = (VeryPDF.ocr2anyCom)System.Activator.CreateInstance(OCRType);

string strReturn = "";
strReturn = OCRCom.ocr2any("-ocrmode 3 -$ XXXX-XXXX-XXXX-XXXX D:\\table.tif D:\\ocr.pdf");
strReturn = OCRCom.ocr2any("-ocr2 -$ XXXX-XXXX-XXXX-XXXX D:\\table.tif D:\\ocr.rtf");
strReturn = OCRCom.ocr2any("-ocr2 -$ XXXX-XXXX-XXXX-XXXX D:\\table.tif D:\\ocr.doc");
strReturn = OCRCom.ocr2any("-ocr2 -$ XXXX-XXXX-XXXX-XXXX D:\\table.tif D:\\ocr.csv");
strReturn = OCRCom.ocr2any("-ocr2 -$ XXXX-XXXX-XXXX-XXXX D:\\table.tif D:\\ocr.xls");
strReturn = OCRCom.ocr2any("-ocr2 -$ XXXX-XXXX-XXXX-XXXX D:\\table.pdf D:\\ocr.txt");
