Fixing Low Quality Scans & Images

The IronTesseract OCR Class provides granular control to C# and .NET developers to add OCR (image and PDF to text) functionality to their applications, and also to fine-tune performance to their specific use cases.

By setting variables, a perfect balance between speed and accuracy can be achieved through working with real-world examples. Settings include: CleanBackgroundNoise, EnhanceContrast, EnhanceResolution, Language, Strategy, RotateAndStraighten, ColorSpace, DetectWhiteTextOnDarkBackgrounds, and InputImageType.
