Angle Property

Summary

Gets or sets the angle of rotation.

Syntax

Objective-C

C++/CLI

Java

Python

public int Angle { get; set; }

@property (nonatomic, assign) NSInteger angle;

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

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

Angle # get and set (HalfToneCommand)

Property Value

The angle of rotation, expressed in hundredths of degrees. A value of 0 produces a horizontal halftone pattern. This property specifies the number of degrees to change the pattern. Positive values rotate the pattern clockwise; negative values rotate the pattern counterclockwise. This value is ignored if the selected halftone pattern is HalfToneCommandType.Rectangle, HalfToneCommandType.Circular, HalfToneCommandType.Random or HalfToneCommandType.UserDefined.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void HalfToneCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   HalfToneCommand command = new HalfToneCommand(); 
   command.Angle = 0; 
   command.Dimension = 2; 
   command.Type = HalfToneCommandType.View; 
   //Halftone the image. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
