MinimumInvertWidth Property

Summary

Gets or sets the minimum width of an area that is considered to be inverted text.

Syntax

Objective-C

C++/CLI

Java

Python

public int MinimumInvertWidth { get; set; }

@property (nonatomic, assign) NSInteger minimumInvertedWidth;

public int getMinimumInvertWidth(); 
public void setMinimumInvertWidth( 
   int intValue 
);

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

MinimumInvertWidth # get and set (InvertedTextCommand)

Property Value

The minimum width of an area that is considered to be inverted text. If InvertedTextCommandFlags.UseDpi is set in the Flags property, units are in thousandths of an inch, otherwise units are in pixels.
