The LEADTOOLS SDK exposes specific settings for the OCR engines it provides via the IOcrSettingManager.
https://www.leadtools.co.../iocrsettingmanager.html

The timeout value for the OmniPage engine is designated by the string "Engine.Timeout". This value can be retrieved by IOcrSettingManager.GetIntegerValue() and IOcrSettingManager.SetIntegerValue().

The default value is 180000 (180 seconds). The code snippet below shows how to change this value to 120000 (120 seconds). Note changes are only effective for the current session.

Code:


using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.OmniPage, false))
{
ocrEngine.Startup(null, null, null, null);
IOcrSettingManager settingManager = ocrEngine.SettingManager;
settingManager.SetIntegerValue("Engine.Timeout", 120000);
ocrEngine.Shutdown();
ocrEngine.Dispose();
}

Note the "Engine.Timeout" value is not an accessible setting for the LEAD engine and it is unable to be modified. However, an OCR operation can still be preemptively cancelled--see this post for using the LEAD engine.
