Asprise C# .NET OCR (optical character recognition) and barcode recognition SDK 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 barcode information from scanned documents.

You can convert images (in various formats like JPEG, PNG, TIFF, PDF, etc.) into editable document formats (Word, XML, searchable PDF, etc.). With our other offering like Asprise Image Scanning SDK (which captures documents from scanners), you can easily implement full document management solutions.
