You have the option to set the parameters for orientation. The orientation parameter determines how the ocr engine will recognize images that are rotated.

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

// Set page orientation to upright.
params = {
    orientation: 'upright'
};

There are 3 options to set the orientation value:

• 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 - 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 - 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 orientation to UPRIGHT, then the OCR output will be incorrect.
