Summary
Specifies how a polygonal shape with crossing lines is filled.
Syntax
C#

typedef NS_ENUM(NSInteger, LTLeadFillMode) {
LTLeadFillModeAlternate,
LTLeadFillModeWinding
};
public final class LeadFillMode
extends java.lang.Enum<LeadFillMode>
public enum class LeadFillMode class LeadFillMode(Enum):
Alternate = 0
Winding = 1
Members
| Value | Member | Description |
|---|---|---|
| 0 | Alternate | The filled area includes the area between odd-numbered and even-numbered polygon sides on each scan line. |
| 1 | Winding | All pixels that are inside the resulting exterior lines are filled. |
