In Linux I think we need mozplugger plugin for viewing pdf files. I just removed and installed mozplugger again (Reference links: http://www.tootips.com/2013/01/how-to-open-pdf-files-inside-chromium.html, http://mozplugger.mozdev.org/) and now it seems to work.
在 Linux 中，我认为我们需要 mozplugger 插件来查看 pdf 文件。我只是删除并重新安装mozplugger（参考链接：http://www.tootips.com/2013/01/how-to-open-pdf-files-inside-chromium.html，http://mozplugger.mozdev.org /) 现在它似乎可以工作了。
In windows we need to install a system pdf reader like acrobat (http://www.adobe.com/in/products/reader.html), as chromium downloads and displays pdf with system PDF viewer (Reference link: http://code.google.com/p/chromium/wiki/ChromiumBrowserVsGoogleChrome).
在 Windows 中，我们需要安装一个系统 pdf 阅读器，如 acrobat ( http://www.adobe.com/in/products/reader.html)，因为 Chromium 下载并使用系统 PDF 查看器显示 pdf (参考链接：http:// code.google.com/p/chromium/wiki/ChromiumBrowserVsGoogleChrome）。
An alternative solution is to open the pdf link in default browser with help of node.js using below script.
另一种解决方案是在 node.js 的帮助下使用以下脚本在默认浏览器中打开 pdf 链接。
Install the node.js open module:
安装 node.js 打开模块：
$ npm install open
use:
用：
var open = require('open');
open('http://www.google.com', function (err) {
if (err) throw err;
console.log('The user closed the browser');
});

If you look at this Ask Ubunutuquestionyou'll see you can actually use Chrome's PDF viewer with Chromium.
如果您查看此Ask Ubunutu问题，您会发现实际上可以将 Chrome 的 PDF 查看器与 Chromium 结合使用。
Chrome has a nice PDF plugin that lets you open in the page, but it's not open source so it's not included with Chromium. You could install Chrome and symlink the plugin, then whenever you update Chrome you would also get that updated in Chromium. Alternatively, you could copy the plugin over to Chromium, and uninstall Chrome, but you won't receive updates that way.
Chrome 有一个不错的 PDF 插件，可以让你在页面中打开，但它不是开源的，所以它不包含在 Chromium 中。你可以安装 Chrome 并符号链接插件，然后每当你更新 Chrome 时，你也会在 Chromium 中更新。或者，您可以将插件复制到 Chromium，然后卸载 Chrome，但您不会以这种方式收到更新。
