  • Deskew using Automatic Angle Detection: It automatically checks if the PDF page is skewed, then corrects the skewed PDF page using a special algorithm. It works only with the scanned text-print image.
  • Deskew Angle Range: Specify the working (deskew) range in degrees. Low values enhance performance. For example, specifying 30 Skew will scan the image searching for pixels inside a range of -15 to 15 degrees. Angle Range can be from 1 to 90. The default is 30.
  • Deskew Sampling Skip: Sampling skip means that only a fraction of the submitted lots are inspected. This mode of sampling is of the cost-saving variety in terms of time and effort. The range can be from 0 to 20. The default is 0. The lower Skip, the higher accuracy but slow speed.
  • Deskew Page DPI: The image DPI that the PDF Page is converted into Image so that PDFill detect the Deskew Angle. The higher DPI, the higher accuracy but slow speed.
