FillMode Property

Summary

Gets or sets a value that indicates how to handle complex crossing lines.

Syntax

C++/CLI

Java

Python

public LeadFillMode FillMode { get; set; }

public LeadFillMode getFillMode(); 
public void setFillMode( 
   LeadFillMode leadFillMode 
);

public: 
property LeadFillMode FillMode { 
   LeadFillMode get(); 
   void set (    LeadFillMode ); 
}

FillMode # get and set (RasterCurve)

Property Value

A LeadFillMode enumeration value that indicates how to handle complex crossing lines.

Remarks

Value	Meaning
LeadFillMode.Winding	All pixels that are inside the resulting exterior lines are in the region.
LeadFillMode.Alternate	The region includes the area between odd-numbered and even-numbered polygon sides on each scan line.
