GS1 Composite Barcodes in C#

Overview

GS1 Composite barcode symbology is a set of 1D and 2D barcodes combinations. The symbology was developed to extend low data density 1D barcodes with 2D component which has more additional information. GS1 Composite consists from two parts: 1D linear barcode containing primary data which can be read with basic scanners and 2D barcode containing supplementary data which qualifies the primary message.

Aspose.Barcode for .Net allows to encode this symbology as EncodeTypes.GS1CompositeBar with GS1CompositeBar parameters which allows to setup 1D and 2D components type and other options. Aspose.Barcode barcode generation engine requires symbol “|” to split 1D and 2D CodeText.

1D component types includes:

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, which are used as 1D component, can encode any ISO/IEC 646 symbol which is allowed to use in encoding GS1 Application Identifier. All other 1D barcodes from 1D components can encode only data in strict format.

2D component types includes:

CC_A – the barcode component, based on MicroPDF417-like symbology.
CC_B – the barcode component, used MicroPDF417 symbology to encode 2D binary data.
CC_C – the barcode component, used PDF417 symbology to encode 2D binary data.

2D Linear Barcode Component Selection

2D component columns amount and type depends from 1D linear component. 2D component columns contains three types: CC_A, CC_B and CC_C. CC_C can be used only with GS1 Code128, all others like CC_A, CC_B can be used with any 1D linear component. Any 2D component can encode ISO/IEC 646 charset which includes:

digits (0-9);
uppercase letters(A-Z);
lowercase letters(a-z);
special symbol FNC1 which is used internally as GS1 Application Identifier splitter;
punctuation symbols (!"%&’()*+,-./:;<=>?_);
space symbol ( )

All symbols can be used freely in non GS1 encoding mode or according GS1 rules, where it is allowed in GS1 Application Identifier.

In the following list we give more detail about every 2D component.

CC_A - is 2D component, based on MicroPDF417-like symbology. Can encode up to 56 digits or any ISO/IEC 646 symbols with variable length. Can be used with any 1D linear component.

//Encode GS1Composite barcode with CC_A 2D component
using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.GS1CompositeBar, "(01)98898765432106(3202)012345|(10)ABCD0123(240)0123456789"))
{
    gen.Parameters.Barcode.XDimension.Pixels = 2;
    gen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.None;
    gen.Parameters.Barcode.GS1CompositeBar.TwoDComponentType = TwoDComponentType.CC_A;
    gen.Parameters.Barcode.GS1CompositeBar.LinearComponentType = EncodeTypes.GS1Code128;

    gen.Save($"{path}GS1Composite2D_CC_A.png", BarCodeImageFormat.Png);
}

CC_B - is 2D component, used MicroPDF417 symbology to encode 2D binary data. Can encode up to 338 digits or any ISO/IEC 646 symbols with variable length. Can be used with any 1D linear component.

//Encode GS1Composite barcode with CC_B 2D component
using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.GS1CompositeBar, "(01)98898765432106(3202)012345|(10)ABCD0123(240)0123456789"))

    gen.Parameters.Barcode.XDimension.Pixels = 2;
    gen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.None;
    gen.Parameters.Barcode.GS1CompositeBar.TwoDComponentType = TwoDComponentType.CC_B;
    gen.Parameters.Barcode.GS1CompositeBar.LinearComponentType = EncodeTypes.GS1Code128;

    gen.Save($"{path}GS1Composite2D_CC_B.png", BarCodeImageFormat.Png);
}

CC_C - is 2D component, used PDF417 symbology to encode 2D binary data. Can encode up to 2361 digits or any ISO/IEC 646 symbols with variable length. Can be used only with GS1 Code128.

//Encode GS1Composite barcode with CC_C 2D component
using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.GS1CompositeBar, "(01)98898765432106(3202)012345|(10)ABCD0123(240)0123456789"))

    gen.Save($"{path}GS1Composite2D_CC_C.png", BarCodeImageFormat.Png);
}

2D Component in non GS1 Mode

Sometimes we need to encode non GS1 data in 2D component. For this you can use property IsAllowOnlyGS1Encoding.

//Encode GS1Composite barcode with not GS1 complaint 2D component
using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.GS1CompositeBar, "(01)98898765432106(3202)012345|Aspose.Barcode"))

    gen.Parameters.Barcode.XDimension.Pixels = 2;
    gen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.None;
    gen.Parameters.Barcode.GS1CompositeBar.TwoDComponentType = TwoDComponentType.CC_C;
    gen.Parameters.Barcode.GS1CompositeBar.LinearComponentType = EncodeTypes.GS1Code128;
    gen.Parameters.Barcode.GS1CompositeBar.IsAllowOnlyGS1Encoding = false;

    gen.Save($"{path}GS1Composite2D_NotGS1TwoDSupplement.png", BarCodeImageFormat.Png);
}

Encode Special Modes for 2D component

2D component data can be encoded in three modes with different compaction ability:

Mode 0 - general-purpose data compaction which can be used to encode any GS1 Application Identifier or non GS1 data with ISO/IEC 646 charset;
Mode 10 which can be used to encode data with GS1 AI 11, 17 and 10 with maximal compaction;
Mode 11 which can be used to encode data with GS1 AI 90 with maximal compaction.

Mode 0

In this mode you can encode any ISO/IEC 646 symbol sequence.

Digits encoding:

//Encode GS1Composite barcode Encodation Method 0: Digits
using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.GS1CompositeBar, "(01)98898765432106|0123456789"))
