Enum Constant Detail

EUCLIDEAN

public static final DistanceTransform.DistanceMetric EUCLIDEAN

Euclidean distance metric where dist = Math.sqrt(dx * dx + dy * dy).

CITYBLOCK

public static final DistanceTransform.DistanceMetric CITYBLOCK

Cityblock distance metric where dist = Math.abs(dx) + Math.abs(dy).

CHESSBOARD

public static final DistanceTransform.DistanceMetric CHESSBOARD

Chessboard distance metric where dist = 1.

Method Detail

values

public static DistanceTransform.DistanceMetric[] 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 (DistanceTransform.DistanceMetric c : DistanceTransform.DistanceMetric.values())
    System.out.println(c);

Returns:

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

valueOf

public static DistanceTransform.DistanceMetric 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
