It May Help You to Make the Right Decision.

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!

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!
