Constructor Detail

Justifier

public Justifier(java.util.Vector justifiables,
                 double width)

Method Detail

justify

public void justify()

shift

public void shift(double xVal)

calcDurationalSpacing

public static double calcDurationalSpacing(double spacingBase,
                                           double duration)

0 lt base lte 1.0

calcDurationalSpacing

public static double calcDurationalSpacing(double duration)

Calculate a non-linear spacing based on duration. Uses duration spacing base

Returns:

base^(ln(1/L))

setDurationalSpacingBase

public static void setDurationalSpacingBase(double base)

base ranges from (0 to 1]. Default is 0.7. Controls how much a note's duration influences its non-linear spacing. High values (like 0.9) result in layout where note duration is less important than low values (like 0.5).

getDurationalSpacingBase

public static double getDurationalSpacingBase()
