All Implemented Interfaces:

Cloneable

public class ImplCode128A
extends ImplCode128

Implementation of Code 128 A. To generate instances, please use one of the newInstance static methods in the Barcode class.

Code 128 A is a subset of Code 128, capable of encoding ASCII characters with values from 0 to 95, covering:

• Control characters (ASCII 0-31), such as NUL, SOH, STX, etc.
• Digits (0-9)
• Upper case letters (A-Z)
• Space character
• Punctuation and special characters: !"#$%&'()*+,-./:;<=>?@[\]^_

In addition, Function Codes (FNC1 to FNC4) can be used within the provided input to meet specific application requirements.

Code 128 A uses an internal checksum included within the barcode symbol but not displayed in plaintext representation.

Parameters:

content - the content to be encoded in the Code 128 A barcode

autoComplete - whether to automatically convert lowercase letters in the content to uppercase letters

appendOptionalChecksum - has no function, as Code 128 A uses a fixed internal checksum which is not optional
