Google Chrome's PDF Rendering Engine Released as Open Source
================================================================================

**Large companies like Google don't really like open source projects, although their Chrome browser is based on Chromium. Now, the PDF rendering engine that is being used in Google Chrome has been released as open source.**
The PDF rendering engine in Google Chrome is called [PDFium][1] and up until now the project has not been opened to the public. It's unclear what made them change their mind, but now users can download the PDFium source.
Even if it's now open source, it's governed by a new BSD license that has some particular conditions. For example, the redistributions of the source code must retain the copyright notice, a list of conditions, and a disclaimer, the reproduction of the binary has to respect the same conditions, and neither the name of the copyright holder nor the names of its contributors may be used to endorse or promote products derived from this software.
Like most of the open source projects, it is available on GitHub and you can easily clone the project with the following command:
git clone https://pdfium.googlesource.com/name
It's unlikely that PDFium will be used in other major projects, but it's good to see that Google is trying to stay friendly with the open source community.

谷歌浏览器使用的 PDF 渲染引擎以开源形式发布
================================================================================

**大型公司,例如谷歌,并不会真的喜欢上开源项目,虽然他们的谷歌浏览器基于开源的 Chromium 浏览器。现在,在谷歌浏览器中所使用的 PDF 渲染引擎以开源形式发布了。**
在谷歌浏览器中所使用的 PDF 渲染引擎是 [PDFium][1] ,迄今为止这个项目都没有向公众发布过。现在还不清楚是什么改变了他们的想法,不过现在用户们可以去下载 PDFium 的源代码了。
虽然 PDFium 现在是开源的,但是它是在一个有特定条件的新 BSD 协议下发布的。例如再次使用源代码必须保留其原有的版权声明、一份条件列表以及一份免责声明。对于二进制文件的再发布需要相同的条件。与此同时,无论是版权持有者还是它的贡献者都不能署名或推广该软件的衍生产品。
就像大多数的开源项目一样,它可以在 Github 上获得,你可以很容易地使用如下命令乃克隆该项目:
git clone https://pdfium.googlesource.com/name
虽然 PDFium 未必能在其他主要项目中使用,但我们很高兴看到谷歌正在试图对开源社区变得友好。
