XTranslation Property

Summary

Gets or sets the amount of image translation along the x-axis (Width).

Syntax

Objective-C

C++/CLI

Java

Python

public int XTranslation { get; set; }

@property (nonatomic, assign) NSInteger xTranslation;

public int getXTranslation(); 
public void setXTranslation( 
   int intValue 
);

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

XTranslation # get and set (ApplyTransformationParametersCommand)

Property Value

The amount of image translation along the x-axis (Width). This value is divided internally by 100. This value must be equal to the one returned from GetTransformationParameters.
