Syntax
C#
Objective-C
C++/CLI
Java
Python
public int GapLength { get; set; } 
@property (nonatomic, assign) NSInteger gapLength; 
public int getGapLength(); 
public void setGapLength( 
   int intValue 
); 
public: 
property int GapLength { 
   int get(); 
   void set (    int ); 
} 
GapLength # get and set (LineRemoveCommand) 

Property Value

Maximum length of a break or a hole in a line. This can be used to remove dotted lines, dashed lines, or lines that have breaks due to scanning. 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.UseDpi is set in the Flags property.
