Posted - Sep 10 2018 : 19:43:00 For general document Deskew, you can use IEVision's OCR getOrientation or TImageEnProc.SkewDetectionFine and SkewDetection.
Other than that there is not a specific method to detect markers, but you could iterate through the scanlines to locate the four corners and then calculate the deskew yourself.
