Method Details

values

public static VideoColor.Matrix[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static VideoColor.Matrix valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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

NullPointerException - if the argument is null

kr

public double kr()

Returns:

the red luma weight, exactly as the recommendation defines it

kb

public double kb()

Returns:

the blue luma weight, exactly as the recommendation defines it

kg

public double kg()

Returns:

the green luma weight, which is 1 - kr() - kb() and is never stored separately
