Today I found a Opensource PDF viewer for Windows base on XPDF, so I wan to let more people know it, thought it still not support CJK Fonts very well.
home page is:

btw, after compressed by UPX290, it will only 514K, really a pretty one, and it support command line, that means you can use it to open pdf in batch file.

What is Sumatra PDF?

Sumatra PDF is a slim, free, open-source PDF viewer for Windows.
Why another PDF viewer?

There’s nothing wrong with Adobe Acrobat… except for annoyingly long startup time. Sumatra PDF is small and starts up fast. Just the way I like it.

It only has minimal set of features, so don’t expect too much. It’s only version 0.3. It does read PDFs but not much more. The future, however, is so bright that you’ll have to wear sunglasses.
Download

Installer: SumatraPDF-0.3-install.exe
Zip file: SumatraPDF-0.3.zip

Here’s how it looks in action:

Getting the sources

Sumatra PDF is just a Windows UI code for poppler pdf rendering library. To get the sources do:

svn –username=anon –password=anon co https://repo.kowalczyk.info/svn/sumatrapdf

Ignore the warnings about missing certificate – this is SSL protocol raising its ugly, mis-design head. You’ll need Visual Studio 2005 to build (or you can re-create the project using a different compiler).
