Serializable, Comparable<TLcdAWTPath.WindingRule>

Enclosing class:

TLcdAWTPath

public static enum TLcdAWTPath.WindingRule
extends Enum<TLcdAWTPath.WindingRule>

Specifies how the interior of a shape is determined for self-intersecting polygons, i.e. how to calculate whether a point is outside or inside the shape.

Enum Constant Detail

WIND_EVEN_ODD

public static final TLcdAWTPath.WindingRule WIND_EVEN_ODD

The odd-even winding rule typically does not fill overlapping regions in self-intersecting polygons.

The rule is as follows: for a given point, draw a straight line from that point in any direction towards infinity. Find all the intersections of the shape with this line. If this number is odd, the point is inside; if even, the point is outside.

WIND_NON_ZERO

public static final TLcdAWTPath.WindingRule WIND_NON_ZERO

The non-zero winding rule typically fills overlapping regions in self-intersecting polygons.

The rule is as follows: for a given point, draw a straight line from that point in any direction towards infinity. Find all the intersections of the shape with this line. Score up the winding number as follows: for every clockwise intersection (the shape passing through the ray from left to right, as viewed from the point) subtract 1; for every counter-clockwise intersection (shape passing from right to left, as viewed from the point) add 1. If the total winding number is zero, the point is outside the shape; otherwise, it is inside.

Method Detail

values

public static TLcdAWTPath.WindingRule[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TLcdAWTPath.WindingRule c : TLcdAWTPath.WindingRule.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TLcdAWTPath.WindingRule valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
