# Configure OCR

In the following examples, OCR is configured to process scanned pages that contain only English or only Japanese text. Providing information about the input can result in a performance improvement, but OCR may fail to recognize text that does not match your configuration. For more information about optimizing OCR, see Optimize OCR Performance.

To configure OCR

- To configure OCR through the .NET API, call the method `Ocr` on your session configuration. For example:

  Copy

      session.Config().Ocr(
          true,
          OCROrientation.Upright,
          OCRTextFindingMode.Document,
          OCRDetectAlphabet.Listed,
          new string[]{ "en", "ja"}
      );
