Colonial has been a satisfied customer of your Spire.PDF dll library for years; having purchased a license in February of 2015.
We use it in a variety of C# applications, both in website Save-As and automated transformative file creation application situations.
Miles ThorntonColonial
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!
Eric BrownChildrenSAL
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!
