Field Detail

RANDOM_COLOR

public static Lang.Producer<Color> RANDOM_COLOR

TRACKING_PIXEL

public static Lang.Producer<BufferedImage> TRACKING_PIXEL

A function that generates a transparent tracking pixel

Method Detail

values

public static Img.F[] 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 (Img.F c : Img.F.values())
    System.out.println(c);

Returns:

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

valueOf

public static Img.F 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

background

public static Lang.Producer<BufferedImage> background(int w,
                                                      int h)

A function that generates a transparent background in rectangular area

Parameters:

w - the width

h - the height

Returns:

a function as described above

randomPixels

public static Lang.Producer<BufferedImage> randomPixels(int w,
                                                        int h)
