Great article! So I had a look at the other products offered by Spice and it looks like the cover a lot, including PDF generation, bar code generation and much more. Do you know how the licensing works and what is free?
They have a list of products like Spire.Doc, Spire.PDF, Spire.XLS, Spire.Presentation that are used to manipulate documents in different formats on .NET or Java platforms. Only the commercial version needs to apply a license to remove the evaluation message on the generated documents, while the free version doesn't need that and there's no evaluation message, but free veison has certain page limitations.
