CutyCapt作爲IECapt的兄弟，可以跨平臺運行，生成的文件格式也多，SVG、PDF、 PS、 PNG、 JPEG,、TIFF,、GIF和BMP，CutyCap依賴于Qt。
一，先安裝Qt47
增加qt47的下載源
vi /etc/yum.repos.d/atrpms.repo
[atrpms]
name=CentOS $releasever – $basearch – ATrpms
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
enabled=1

#yum update
yum install qt47
yum install qt47-devel
yum install qt47-webkit
yum install qt47-webkit-devel
可能的錯誤：
warning: qt44-x11-4.4.3-10_4.el5.x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 66534c2b
解决：
yum -y installqt-devel*
可能的錯誤：某些衝突conflict
qt47-x11 conflicts with qt-x11
qt47-x11 conflicts with qt-x11
解决：通過yum remove 卸載衝突的內容
yum remove qt-devel
yum remove qt-x11
二，安裝 CutyCapt
下載代碼，這裏需要用到SVN，如果沒有安裝，可以使用命令安裝：
#yum install subversion
svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
mv cutycapt/CutyCapt /usr/local/cutycapt
cd /usr/local/cutycapt
qmake
可能會出現的錯誤：
-bash: qmake: command not found
解决：
qmake-qt47
make
此處可能會報錯：
make: *** [CutyCapt] Error 1
解决：
yum update sqlite #如果是6.0,默認就是3.6
再次執行make即可！
三、下載和安裝X-Server
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
出現錯誤提示：CutyCapt: cannot connect to X server :99
可以使用命令安裝：
yum install xorg-x11-server-Xvfb
四，安裝中文包
yum install fonts-chinese
五，運行 CutyCapt進行截圖：執行以下命令，如果沒有錯誤，就會在當前目錄下面保存截圖。
/usr/local/cutycapt/xvfb-run.sh –server-args=”-screen 0, 1024x768x24″ /usr/local/cutycapt/CutyCapt –url=http://www.163.com –out=163.jpg
六 ，其他一些相關問題
Q:出現-bash: xvfb-run: command not found 或 xauth : command not found
安裝 yum install Xorg xauth xorg-x11-fonts*（Xorg,xauth,xorg-x11-fonts* 這是三個不同的工具，每個都需要單獨運行yum install來安裝）
Q:錯誤提示：”mktemp: too few X’s in template `Xauthority’.”
找到　AUTHFILE=$(mktemp -p “$XVFB_RUN_TMPDIR” Xauthority)
修改爲：AUTHFILE=$(mktemp -p “$XVFB_RUN_TMPDIR” Xauthority.XXXXXXXX)
Q:錯誤提示：CutyCapt: cannot connect to X server :99
確認server-args參數是否正確，修改xvfb-run.sh脚本中SERVERNUM=99 改爲SERVERNUM=0
Q：截出來的圖片沒有中文字，需要安裝中文字體
yum install cjkuni-ukai-fonts cjkuni-uming-fonts -y
Q：由于截屏的是整個網站的頁面，只需要第一屏幕
convert -crop 1024×768+0+0 163.jpg 1632.jpg
Q：縮小圖片
convert -resize 40%x40% 1632.jpg 1632.jpg
Q：CutyCapt: cannot connect to X server
網上很多都是要在裝個xvfb-run.sh的，其它不用這麽麻煩
echo “export DISPLAY=’:1.0′” >> /etc/profile
source /etc/profile
vncserver
# ./CutyCapt –help
不過每次都輸入export LIBXCB_ALLOW_SLOPPY_LOCK=1有點麻煩，大神給了個解决方法！
cat > run
vi run
輸入
export LIBXCB_ALLOW_SLOPPY_LOCK=1
../../xvfb-run.sh ./CutyCapt –url=$1 –out=$2 –body-string=$3
保存退出
chmod +x ./run
./run http://www.baidu.com test.jpg, utf-8
依次輸入 $1 http://www.baidu.com $2 圖片名 $3字體
Q：環境變量配置
# vi /etc/profile 未尾加入以下代碼
export QTDIR=/usr/lib/qt44
export QTLIB=/usr/lib/qt44/lib
export QTINC=/usr/lib/qt44/include
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$QTDIR/bin:$PATH
# source /etc/profile
