You have the option to set the parameters for PageOrientation.

In the code snippet example below, the page orientation is set to UPRIGHT:

RecognitionParameters parameters = new RecognitionParameters();
parameters.setPageOrientation(PageOrientation.UPRIGHT);

There are 3 options to set the PageOrientation enumeration:

• DETECT - PageOrientation.DETECT will recognize the angle (0°, 90°, 180°, 270°) and maintain the same orientation for the output. Please see the examples below:
  
  90° detection

  Original Image 90°	Output PDF 90°

  
  180° detection

  Original Image 180°	Output PDF 180°

• REORIENT - PageOrientation.REORIENT will recognize the angle (0°, 90°, 180°, 270°) and provide an UPRIGHT output. Please see example below:
  
  90° detection

  Original Image 90°	Output PDF

• UPRIGHT - PageOrientation.UPRIGHT will recognize an UPRIGHT image and provide an UPRIGHT output. Please see example below:
  
  

  Original Image	Output PDF

  
  
  Please be aware, if the original image is not upright and you set the PageOrientation to UPRIGHT, then the OCR output will be incorrect.
