一个使用pyQt4里的QtWebkit实现的命令行的web截图软件,可用于服务器端的web截图
貌似是个比较新的项目，以前找过类似的工具,没有多好用的，但是这个真的很好用，看一下参数就知道了

使用举例:
使用之前安装依赖的包

sudoapt-getinstall python-qt4sudo apt-get install python-qt4Copy Code 

OK,可以用了,假如在用ubuntu桌面版的话就很简单了

#加上运行权限
chmod +x ./webkit2png.py
#高度设置为0,就可以获得整个页面的截图了
./webkit2png.py -g10240 http://bluehua.org -o test.png#加上运行权限 chmod +x ./webkit2png.py#高度设置为0,就可以获得整个页面的截图了./webkit2png.py -g 1024 0 http://bluehua.org -o test.pngCopy Code 

假如运行在服务器上，没有x环境，则需要安装一些额外的依赖包

#安装xvfb用于虚拟X环境
apt-getinstall xvfb
#安装中文字体
apt-getinstall xfonts-wqy
#配置字体
fontconfig-voodoo -f-s zh_CN#安装xvfb用于虚拟X环境apt-get install xvfb#安装中文字体apt-get install xfonts-wqy#配置字体fontconfig-voodoo -f -s zh_CNCopy Code 

运行时需要加额外的参数

#x选项用于指定虚拟出来的X桌面的尺寸
./webkit2png.py -x1024768-g10240 http://bluehua.org -o test.png#x选项用于指定虚拟出来的X桌面的尺寸./webkit2png.py -x 1024 768 -g 1024 0 http://bluehua.org -o test.pngCopy Code 

恩，其实我找这个东西的目的是想在服务器端获取一个页面的实际渲染宽度，目的达成~
