Class QColor

java.lang.Object

net.sourceforge.plantuml.quantization.QColor

public final class QColor
extends Object

An RGB representation of a color, which stores each component as a double in the range [0, 1]. Values outside of [0, 1] are permitted though, as this is convenient e.g. for representing color deltas.
