L_LTOCR_APIL_INTEXT_FUNCTIONL_OcrEngine_GetAutoRecognizeManager(引擎、autoRecognizeManager)
返回一个句柄到OCR自动识别管理器。
OCR引擎的句柄。
指针L_OcrAutoRecognizeManager要更新的句柄。
| 价值 | 意义 |

| < 1 | 发生错误。指返回代码． |
该函数返回OCR引擎自动识别管理器的句柄，允许您执行一次“发射并忘记”OCR操作。
的L_OcrAutoRecognizeManager提供使用一次调用将单个或多页图像文件转换为OCR文档的方法。当引擎的默认设置提供了所需的最终文档，并且不需要进行微调时，可能需要这样做。
的L_OcrAutoRecognizeManager还提供回调支持来监控各种OCR操作，记录和跟踪，以及允许用户在任何时候中止。
