public class Moveleft
extends AbstractBoxPrimitive

This class provides an implementation for the primitive \moveleft.

The Primitive \moveleft

The primitive \moveleft takes a box and a length and moves it leftwards by the amount specified by the length. If the length is negative then the move is done rightwards.

The primitive \moveleft is the counterpart to \moveright.

Syntax

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

Examples

    \moveleft 2em \hbox{abc}  
    \moveleft -1pt \hbox to 120pt {abc}  
    \moveleft 2mm \hbox spread 12pt {abc}
