Angle Property

Summary

Amount by which the method rotates the image.

Syntax

Objective-C

C++/CLI

Java

Python

public int Angle { get; }

@property (nonatomic, assign, readonly) NSInteger angle;

public int getAngle(); 
public void setAngleRange( 
   int intValue 
);

public: 
property int Angle { 
   int get(); 
}

Angle # get  (DeskewCommand)

Property Value

Amount by which the method rotates the image. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise. Valid values range from -2000 through 2000.

Example

Run the DeskewCommand on an image and straightens it.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void AnglePropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   DeskewCommand command = new DeskewCommand(); 
   //Deskew the image. 
   command.Flags = DeskewCommandFlags.DeskewImage | DeskewCommandFlags.FillExposedArea; 
   command.FillColor = new RasterColor(255, 255, 0); 
 
   command.Run(image); 
 
   MessageBox.Show("The Angle = " + command.Angle.ToString()); 
 
}
