All Implemented Interfaces:
Code, Localizable, java.io.Serializable
public class Kern
extends AbstractCode

This class provides an implementation for the primitive \kern.

The Primitive \kern

This primitive produces a horizontal or vertical kerning. This is a (minor) adjustment of the position. The meaning depends on the current mode of the typesetter. In vertical modes it means a vertical adjustment. Otherwise it means a horizontal adjustment.

Syntax

The formal description of this primitive is the following: 
    ⟨kern⟩
      → \kern ⟨dimen⟩

Examples

    \kern 12pt  
    \kern -3mm  
    \kern -\dimen123

The effect of the primitive is that a KernNode is is sent to the typesetter.
