Coffee in Code out---編程的一種境界

1、第一步當然是先下載源碼了，下載地址：http://www.ijg.org/
2、解壓后所有的東西都在一個文件夾里了，如果有耐心可以看一下自帶的說明文檔（install.txt）
3、其中有一段在vs2010下的說明

==================================================================
Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10):

We include makefiles that should work as project files in Visual Studio2010 or later.  There is a library makefile that builds the IJG library
as a static Win32 library, and application makefiles that build the sample applications as Win32 console applications.  (Even if you only want the
library, we recommend building the applications so that you can run the self-test.)

To use:
1. Open the command prompt, change to the main directory and execute the  command line

   This will move jconfig.vc to jconfig.h and makefiles to project files.   (Note that the renaming is critical!)

2. Open the solution file jpeg.sln, build the library project.
   (If you are using Visual Studio more recent than 2010 (v10), you'll  probably get a message saying that the project files are being updated.)
3. Open the solution file apps.sln, build the application projects.
4. To perform the self-test, execute the command line
 

5. Move the application .exe files from `app`\Release to an   appropriate location on your path.

Note:
There seems to be an optimization bug in the compiler which causes the self-test to fail with the color quantization option.
We have disabled optimization for the file jquant2.c in the library project file which causes the self-test to pass properly.

=============================================================================================

簡單的操作其實也就兩行，一個是生成vs2010的工程文件 NMAKE /f makefile.vc  setup-v10
運行結果如下：

然后打開jpeg.sln，直接編譯就ok了
