  +--org.omegahat.Graphics.Primitives.Unit

public class Unit

extends java.lang.Object

Units in which lengths can be specified.

The class constants define which units are being supplied; for example Unit.CM for centimetres. These constants can be supplied as arguments or embedded in UDouble objects.

Units can be absolute: centimetres, inches, or lines of text (the last depending on the associated fontsize). They can also be relative: native units are relative to the scale of the corresponding graphical element; NPC are relative to the normalized parent co-ordinates. See the graphics engine paper for more discussion.
