我正在尝试使用flexicapture SDK进行验证步骤。
当我试图从IText对象获得识别的字数时，它返回0（零）。
int wordCount = text.getRecognizedWordsCount（）;
wordCount在这里为零......
Work flow as below:
1.Load the engine
2.create project
3.creating and adding images in batch obtained from project ( project.getBatches().AddNew("TestBatch") )
4.Recognize batch using batch object (batch.Recognize(null, RecognitionModeEnum.RM_ReRecognizeAll,null) )
5. Start verification session
6. enable context verification and disable group verification
7. Get work set from session
8. FOR ALL Work Set: get verification group
9. FOR ALL Verification group: get verification object
10. FOR each verification object: Get Fields ( under context verification )
11. obtained IField object
12. get IFieldValue object from Field object
13. Get IText object ( IText text = fieldValue.getAsText() )
14. get recognized word count ( int wordCount = text.getRecognizedWordsCount() )
here i'm getting 0 as result ( wordCount = 0 )
请建议一些解决方案; 我的主要任务是获取每个fieldValue，我们需要每个字或每个字符的置信度。

请在文档处理之前将IEngine :: EnableRecognitionVariants设置为TRUE。
