iTextSharp许可 [英] iTextSharp Licensing

问题描述

我们想在我们的一个项目中使用iTextSharp DLL提取PDF文本，但是我有第二个想法将其发布到生产环境中，因为我读到某个地方，我们需要购买商业许可才能使用iTexttSharp.这是真的?我们将只使用DLL，并且不会进行任何更改，是否还需要购买许可证?

We would like to use iTextSharp DLL in one of our project to extract PDF text but I'm having 2nd thought to release it to production because I read somewhere that we need to purchase a commercial license for us to be able to use iTexttSharp. Is this true? We will just consumed the DLL and we will not change anything, do we still need to buy a license?

预先感谢！

推荐答案

iText是根据AGPL发布的免费软件.这意味着它可以免费使用，前提是您还可以在同一许可证下免费发布项目的源代码.一旦您开始以不同的许可证提供代码或项目(例如，在SaaS产品的上下文中)，则应购买商业许可证.一分钟视频中对此进行了解释，这是我10月28日的JavaOne演讲的主题: IANAL:开发人员应了解有关IP和法律的内容.您会注意到，我们已经成功地上了法庭，以确保遵守开放源代码许可证.

iText is free software released under the AGPL. This means that it can be used for free on condition that you also release the source code of your project for free under the same license. As soon as you start offering the code or the project (e.g. in the context of a SaaS offering) under a different license, then you should purchase a commercial license. That is explained in a one-minute video and it's the subject of my JavaOne talk on October 28th: IANAL: what developers should know about IP and legal. You'll notice that we have successfully went to court to make sure that the open source license was honored.
