Enhancing page images

The PDF Editor can enhance the quality of PDF documents created from image files. Depending on the type of an input image, the program will select the appropriate image enhancement algorithms. Besides automatic image enhancement, the PDF Editor can correct page orientation, skew, distorted text lines and other defects, and make characters look smoother with ABBYY PreciseScan technology.

You can specify enhancement options in the Image Enhancement dialog box (click Edit > Enhance Page Images... to open this dialog box).

  • Correct page orientation Select this option if you want the program to detect and correct page orientation automatically.
    For best recognition results, a page should have the standard orientation, i.e. with horizontal text lines and top-to-bottom reading order. Otherwise, the document may be recognized incorrectly.
  • Deskew images and correct image resolution Select this option if you want the program to run a number of image processing routines on your images.
    Depending on the type of an input image, the program will select the image corrections to apply, such as skew correction, correction of trapezoid distortions, or adjustment of image resolution.
    This operation may take some time to complete.
  • Apply ABBYY PreciseScan to smooth characters on images Select this option if you want to apply ABBYY PreciseScan technology, making the characters less pixelated when you zoom in.

Be sure to select the right OCR languages. See also: Document features to consider prior to OCR.
