Thank you so much for the information and the hotfix of Spire.Doc!
I just tested the hotfix and all issues seem to be resolved. I am very happy that your developers were able to solve these layout problems (to be honest, I didn't expect the problems could be solved).

I was searching for a way to inject Barcodes into our generated Documents. So i found the Spire.BarCode for .NET library for .Net developers. I've tried it and i was really impressed of how easy it is to use it. We are now using 1 D Barcodes and the 2 D PDF417 Barcode.
Thanks very much for developing such a great Library and all for free.

Our team was in need of a .NET utility that would allow us to generate barcode images used for emailing receipts.
Spire.Barcode not only provided the ability to generate barcodes and save them as images, but offers a range of customization that suited our needs perfectly.
The fact that these services are completely free is almost too good to be true!
