NET Library for Tesseract called IronTesseract.įully documented with IntelliSense support. Work with the command line EXE - difficult to deploy and constantly interrupted by virus scanners and security policies.Ī managed and tested.Work with Interop layers - many that are found on GitHub are out of date, have unresolved tickets, memory leaks, and Console warnings.Even low-resolution images generally work with a high degree of accuracy in your program. We have implemented multithreading to make use of the multi-core processors that most machines now use. NET Tesseract DLL works accurately and at speed for most images out of the box. Google Tesseract can perform fast and accurate results if properly tuned and input images have been preprocessed using Photoshop or ImageMagick. Drawing, Stream, and Byte Array are included for every file format. PIX objects are not managed memory - and failure to handle them with care in C# results in memory leaks. Only accepts Leptonica PIX image format which is an IntPtr C++ object in C#. Users often achieve 99.8-100% accuracy with minimal configuration. In addition, Tesseract will also take a very long time to process that document before providing you with nonsensical information. If Tesseract encounters an image that is rotated, skewed, is of a low DPI, scanned, or has background noise, it becomes almost impossible for Tesseract to get data from that image. Why IronOCR Is Better Than Tesseract: ACCURACY TESSERACT: PM > Install-Package IronOcr Step 2: Apply Your License Key Set your IronOCR license key using codeĪdd this code to the startup of your application before IronOCR is used.
