OCR Files to be Included With Your Application

Files for redistribution are installed by the LEADTOOLS setup. For more information on the installation directory structure or redistributing your application, refer to Installation Directory. Unless otherwise noted, file names are the same for both Win32 and x64 versions.

About LEADTOOLS OCR Engines

The OCR files that need to be included with your application depend on the OCR and draw engines being used, as well as the platforms on which they will be deployed.

There are three OCR Engines:

There are two draw engines:

LEAD OCR Engine

The LEAD OCR engine can use either draw engine. The DefaultEngine for Windows is an internal rendering engine which uses Windows GDI/GDI+. It produces the fastest results for Windows. Use the DefaultEngine when creating Windows-only applications.

For other platform environments (platforms such as Linux, Android, macOS, iOS, and Universal Windows Platform (UWP), specify the DrawEngineType.Multiplatform. It, too, is an internal rendering engine, but uses code independent of the operating system. When specified, this engine will always produce the same exact rendering results on other platforms that it produces on Windows platforms.

Note: The LEAD OCR engine is the only engine that can be used when targeting platforms other than Windows.
