LEADTOOLS provides fast and highly accurate Optical Character Recognition SDK technology for .NET (C# & VB), C/C++, iOS, macOS, Java, and web. With extensive support for more than forty character sets, the toolkit can be used to rapidly develop robust, scalable, and high-performance recognition and document processing applications that extract text from scanned documents and convert images to text-searchable formats such as PDF, PDF/A, DOC, DOCX, XML, and XPS.
Does your application require document recognition or conversion, but its implementation language is preventing you from using LEADTOOLS directly? Consider using the LEADTOOLS Cloud Services Web API instead. It is a high-powered and scalable Web API. Its hassle-free interface can be used to integrate advanced OCR, barcode, MICR, and document conversion into any application.
Choosing which draw engine to use in an application depends, in part, on which platforms the application is targeted for deployment:
If an application will be deployed exclusively to Windows platforms, use DrawEngineType.DefaultEngine. It is based on Windows GDI/GDI+ and produces the fastest rendering.
If an application will be deployed to both Windows and non-Windows platforms (such as Linux, Android, macOS, iOS, and Universal Windows Platform (UWP)), use DrawEngineType.MultiplatformEngine. This ensures identical rendering across all platforms.
