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).

Our group was looking for a cost-effective way to add reliable barcode generation to our web application. We tried some free ones that we found to be inaccurate and put our customers at risk.
Spire.Barcode for .Net has proven to pass our test cases as well as come with a free license. Couldn't be happier!

It seems your Spire.PDFViewer component was precisely what we needed. And your demo included in the installer was very much helpful.
Our solution including your Pdf viewer is fine for now.
