目的是想在服务器端生成某个网页的缩略图。Google了好久，发现一个好开源东西：CutyCapt。

系统：CentOS 5.5
官网：http://cutycapt.sourceforge.net/
依赖：QT http://www.qtsoftware.com/

附缩略163.com图，虽然说字体渲染的效果一般，但是看起来还凑合 :)

首次是在Debian下测试的，很顺利。换了CentOS不是太爽。具体安装和使用步骤如下：

1. 下载RPM包

(64位)
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-x11-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-devel-4.4.3-10_4.el5.x86_64.rpm

(32位)
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-4.4.3-10_4.el5.i386.rpm
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-x11-4.4.3-10_4.el5.i386.rpm
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-devel-4.4.3-10_4.el5.i386.rpm

2. 安装 qt-devel 依赖包

yum install libXi-devel
yum install libXinerama-devel

3. 安装 qt 相关

rpm -ivh qt44-4.4.3-10*
rpm -ivh qt44-x11-4.4.3-10*
# rpm -e qt-devel --nodeps --allmatches
rpm -ivh qt44-devel-4.4.3-10*

4. 修改 /etc/profile，最后并：source /etc/profile

export QTDIR=/usr/lib64/qt44
export QTLIB=/usr/lib64/qt44/lib
export QTINC=/usr/lib64/qt44/include
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$QTDIR/bin:$PATH

5. 安装 cutycapt

svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
mv cutycapt/CutyCapt /usr/local/CutyCapt
cd /usr/local/CutyCapt
qmake
make

6. 安装模拟 x-server 服务端

wget http://www.flexthinker.com/wp-content/uploads/2009/11/xvfb-run.sh.txt
mv ./xvfb-run.sh.txt /usr/local/CutyCapt/xvfb-run.sh
chmod u+x /usr/local/CutyCapt/xvfb-run.sh

7. 开始欢快的截图吧

/usr/local/CutyCapt/xvfb-run.sh --server-args="-screen 0, 1024x768x24" /usr/local/CutyCapt/CutyCapt --url=http://www.163.com --out=163.jpg

8. 如果看不到汉字或乱码，需要安装chinese字体

yum install fonts-chinese

9. 由于截屏的是整个网站的页面，只需要第一屏幕

convert -crop 1024x768+0+0 163.jpg 1632.jpg

10. 缩小图片

convert -resize 40%x40% 1632.jpg 1632.jpg
