Flags Property

Summary

Gets or sets the flags that indicate whether to deskew the image and which background color to use.

Syntax

C++/CLI

Python

public DeskewDetectionDataFlags Flags { get; set; }

public:  
   property DeskewDetectionDataFlags^ Flags 
   { 
      DeskewDetectionDataFlags^ get() 
      void set(DeskewDetectionDataFlags^ value) 
   }

Flags # get and set (DeskewDetectionData)

Property Value

Flags that indicate whether to deskew the image, which background color to use, whether to deskew the image if the skew angle is very small, which type of interpolation to use, whether the image contains mostly text, and whether to use normal or fast rotation.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing; 
 
public void DetectDeskewOrientationCommandExample() 
{ 
   // Load an image  
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"Forms\Forms to be Recognized\OCR\FCC-107_OCR_Filled.tif")); 
   // artificially skew the image 7 degrees and rotate it 90 degrees 
   new RotateCommand(-97 * 100, RotateCommandFlags.None, RasterColor.White).Run(image); 
   // Prepare the command  
   DetectDeskewOrientationCommand command = new DetectDeskewOrientationCommand(); 
   // Detect/correct skew and orientation, filling with black 
   command.DeskewDetection.FillColor = RasterColor.Black; 
   command.DeskewDetection.AngleRange = 2000; 
   command.DeskewDetection.AngleResolution = 20; 
   command.DeskewDetection.Flags = DeskewDetectionDataFlags.DocumentAndPictures | DeskewDetectionDataFlags.RotateBicubic; 
   command.Flags = DetectDeskewOrientationCommandFlags.None; 
   command.OrientationDetection.Flags = OrientationDetectionDataFlags.None; 
   command.Run(image); 
   Assert.IsTrue(command.DeskewDetection.Angle > 600 && command.DeskewDetection.Angle < 800 
      && command.OrientationDetection.Angle == 90); 
}
