Incorrect GIF produced by Aspose BarCode


the attached QR code in GIF format has been produced by Aspose BarCode.

The byte at position 0xB is the background color index. Since the byte at position 0xA indicates the presence of a global color table, the background color index must be valid. However, the global color table only has 2 entries (6 bytes) while the background color index is 0xFF, which is plainly out of range.

Please either eliminate the global color table altogether or ensure that the background color index is correct.


Hi Mario,

Thank you for contacting support. Are you using the latest version of Aspose.BarCode for Java 6.8.0? If so, then please provide us your sample code. Otherwise, please use the latest version 6.8.0 and let us know how it goes on your side. It’ll help us to be more specific. We’ll take a closer look and reply you accordingly.

Hi Imran,

I’m on 6.8.0.

I don’t understand why you need the code that produces the barcode. The error is in the .gif format, not in the barcode, so it has nothing to do with how I generate the barcode but on the part of the library that produces the .gif. Anyway, here it is:

public static void main(String[] args) throws Exception {
License license = new License();
license.setLicense(“path to licence”);
BarCodeBuilder b = new BarCodeBuilder();
b.setMargins(new MarginsF(1, 1, 1, 1));
FileOutputStream os = new FileOutputStream(“path for result”);
b.save(os, BarCodeImageFormat.Gif);
