Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The GraphicsPathWinding class provides values for the flash.display.GraphicsPath.winding property and the flash.display.Graphics.drawPath() method to determine the direction to draw a path. A clockwise path is positively wound, and a counter-clockwise path is negatively wound:

positive and negative winding directions

When paths intersect or overlap, the winding direction determines the rules for filling the areas created by the intersection or overlap:

a comparison of even-odd and non-zero winding rules

Constant Detail

EVEN_ODD

Constant
public static const EVEN_ODD:String = "evenOdd"

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Establishes the even-odd winding type. The even-odd winding type is the rule used by all of the original drawing API and is the default type for the flash.display.Graphics.drawPath() method. Any overlapping paths will alternate between open and closed fills. If two squares drawn with the same fill intersect, the area of the intersection is not filled. Adjacent areas are not the same (neither both filled nor both unfilled).

NON_ZERO

Constant 
public static const NON_ZERO:String = "nonZero"

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Establishes the non-zero winding type. The non-zero winding type determines that when paths of opposite winding intersect, the intersection area is unfilled (as with the even-odd winding type). For paths of the same winding, the intersection area is filled.
