Variance Property

Summary

Gets or sets the amount of width change that is tolerated between adjacent line slices.

Syntax

Objective-C

C++

Java

public int Variance { get; set; }

Public Property Variance As Integer

@property (nonatomic, assign) NSInteger variance

public int getVariance() 
public void setVariance(int value)

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

Property Value

Amount of width change that is tolerated between adjacent line slices. If LineRemoveCommandFlags.UseDpi is set in the Flags property, units are in thousandths of an inch, otherwise units are in pixels. This property is valid only if LineRemoveCommandFlags.UseVariance is set in the Flags property. For example, the following horizontal line is 30 pixels in length (X represents a pixel)

If Variance is 2 pixels (i.e. tolerate width changes of 2 pixels or less), the first 10 columns and the last 10 columns of the line will be removed. The middle 10 columns will be unchanged. This helps preserve characters that intersect a line that is being removed.

Example
