Generating GS1 DataBar Expanded Stacked but can not pass the GS1 Barcode verification

Thank for the version number. Do you have the rough release time in the plan?


It will be released before the end of coming week.

Wonderful, Thank you for the update!


You are welcome.

Ok it will be added to next 20.10 release(October), because there were some problems. Too complicated data encoding with different variables. It is already ready, bat it needs more tests to be assured in correct encoding/decoding.

Wondering if you can share the testing library(Java version) with me? so I can verify the GS1 Databar image can passed GS1 Barcode verification or not?

Thank you in advance for your support.



As we told you, since we need to perform extensive testing for confirmation on correct encoding/decoding, so we might not provide the hotifix now. Anyays, we will still check if we could provide the fix for your testing for the time being.

Hopefully, the October releases of BarCode library (.NET and JAVA) will be done in the second half of this month.

Here are some of generated images for testing purposes, You can check them with utility
Issue37615.zip (294.3 KB)

Is any new release scheduled?


The code already added to 20.10 .Net release and will be produced in Java version in the middle of November.

Hi All,

Is the java version license working with the .net libaray?


No, but you can request temporary license

Hi All,

In the new 20.10 release how can i set a quiet zone for UPC-A? is the below code correct?


BarcodeGenerator builder = new BarcodeGenerator(EncodeTypes.UPCA);

You can do this even in 19.9 version

#include <Generation/EncodeTypes/SymbologyEncodeType.h>
#include <Generation/EncodeTypes/EncodeTypes.h>
#include <BarCode.Generation/BarcodeGenerator.h>
#include <BarCode.Generation/GenerationParameters/BaseGenerationParameters.h>
#include <BarCode.Generation/GenerationParameters/BarcodeParameters.h>
#include <BarCode.Generation/GenerationParameters/CodetextParameters.h>
#include <BarCode.Generation/GenerationParameters/Padding.h>
#include <BarCode.Generation/GenerationParameters/CodetextParameters.h>
#include <BarCode.Generation/Helpers/Unit.h>
#include <Generation/BarCodeImageFormat.h>

void GenerateUPCA(std::wstring& folder)
    const System::String codeText = u"01234567891";
    System::SharedPtr<Aspose::BarCode::Generation::BarcodeGenerator> barcodeGenerator = System::MakeObject<Aspose::BarCode::Generation::BarcodeGenerator>(Aspose::BarCode::Generation::EncodeTypes::UPCA, codeText);
    //set left right padding
    //remove codetext if we need this
    barcodeGenerator->Save(System::String::FromWCS(folder + L"upca.png"), Aspose::BarCode::BarCodeImageFormat::Png);
    std::wcout << L"Barcode generated!\n";

Just want to follow up if the below issue have been addressed in the 20.10 release java version

Hi Everyone.

I am creating a new thread to track the problem on generating the DataBar Expanded Stack barcode.
the similar issue was dicussied in Reading GS1 DataBar Expanded Stacked as well. but it was mix up with other topic

The problem is for the barcode (01)00628250992083(13)200828(10)P200004

The FNC1 would be scanned after (10)P in GS1 Databar Expanded Stack. we are using the hard scanner. I have attached the GS1 verification report and image in another thread.

I want to confirm if the issue have been log as a bug in your end. if so when it is fix ready?

This is a very critical issue for us.


We have noted your inquiry and will share our feedback soon.

Currently it is a part of 20.10 Net release, and I watched the java code, the changes have not implemented.

Thank you for confirming this. Do you have a plan to release the fix in java version? Our team has been waiting for this fix about a few month.

Thank you in advance for your help.


I saw a new release 20.11 would you please suggest if the fix is in 20.11 java release.


I see in the code new Databar Expanded data encoder, so I think yes.
