GS1 Composite Barcodes in JavaScript

Overview

The GS1 Composite barcode symbology is a combination of 1D and 2D barcodes. This symbology was designed to enhance the data capacity of low-density 1D barcodes by including a 2D component for additional information. A GS1 Composite barcode consists of two parts: a 1D linear barcode containing primary data that can be read by basic scanners and a 2D barcode containing supplementary data that qualifies the primary message.

Aspose.BarCode for JavaScript via C++ supports encoding this symbology as EncodeTypes.GS1CompositeBar using GS1CompositeBar parameters to configure the 1D and 2D component types and other settings. The barcode generation engine requires a “|” symbol to separate the 1D and 2D CodeText.

1D Component Types

The 1D component types include:

EAN barcodes: EAN8, UPCA, EAN13, UPCE.
DataBar barcodes: Databar OmniDirectional, Databar Stacked OmniDirectional, Databar Stacked, Databar Limited, Databar Expanded, Databar Expanded Stacked.
GS1 Code128 barcode.

Databar Expanded, Databar Expanded Stacked, and GS1 Code128 barcodes used as 1D components can encode any character supported by ISO/IEC 646 for encoding GS1 Application Identifier. Other 1D barcodes in 1D components only support strict format data encoding.

2D Component Types

The 2D component types include:

CC_A – based on MicroPDF417-like symbology.
CC_B – uses MicroPDF417 symbology for encoding 2D binary data.
CC_C – uses PDF417 symbology for encoding 2D binary data.

2D Linear Barcode Component Selection

The number and type of 2D components depend on the 1D linear component used. 2D components come in three types: CC_A, CC_B, and CC_C. The CC_C component can only be used with GS1 Code128, while CC_A and CC_B can be used with any 1D linear component.

All 2D components can encode characters from the ISO/IEC 646 charset, which includes:

Digits (0-9)
Uppercase letters (A-Z)
Lowercase letters (a-z)
Special symbol FNC1, used internally as a GS1 Application Identifier separator
Punctuation symbols (!"%&’()*+,-./:;<=>?_)
Space symbol ( )

These symbols can be used freely in non-GS1 encoding mode or according to GS1 rules where permitted in a GS1 Application Identifier.

2D Component Details

CC_A – A 2D component based on MicroPDF417-like symbology. It can encode up to 56 digits or any ISO/IEC 646 symbols with variable length. This component can be used with any 1D linear component.

Encode Special Modes for 2D Component

Data for the 2D component can be encoded in three different modes, each offering varying levels of data compaction:

Mode 0: General-purpose data compaction that allows encoding any GS1 Application Identifier or non-GS1 data using the ISO/IEC 646 charset.
Mode 10: Used for encoding data with GS1 Application Identifiers (AIs) 11, 17, and 10 with maximum data compaction.
Mode 11: Used for encoding data with GS1 AI 90 with maximum data compaction.

Mode 0

This mode allows encoding any sequence of ISO/IEC 646 symbols.
