Inserted barcode is not visible in pdf

Hi. I’m using aspose pdf in .NET to put barcode insert pdf document. There is now error in program. PDF is growing in size. I can even read image of barcode programmatically. But when I open pdf, inserted image is invisible. This problem is limited to parts of documents. In many cases there is no problem and barcode is visible.


Thanks for contacting support.

Would you please share you sample input PDF document with Barcode image. Also, please share the sample code snippet you are using. We will test the scenario in our environment and address it accordingly.

Thanks for sharing sample code snippet and files.

We have tried to test the code snippet which you have shared with us and noticed that a class named BarcodeLib has missing definition. Which was why we were unable to test the scenario. Would you please share its complete definition with us so that we can try to reproduce the issue which you are facing at you side.
