jar包地址 http://downloads.jmagick.org/6.3.9/
我在window下使用的是 jmagick-win-6.3.9-Q8.zip 和 ImageMagick-6.3.9-0-Q8-windows-dll.exe
linux下使用的是 JMagick-6.2.6-0.tar.gz 和 ImageMagick-x86_64-pc-linux-gnu.tar.gz
doc地址 http://downloads.jmagick.org/jmagick-doc/
windows
一 . 安装 ImageMagick-6.3.9-0-Q8-windows-dll.exe
二 . 将 安装目录下 “C:/Program Files/ImageMagick-6.3.9-Q8/ ”(按自己所安装的目录找) 下的所有dll文件 copy 到系统盘下的 “C:/WINDOWS/system32/”文件夹里
三 . 配置环境变量
再环境变量path里添加新的值 “C:/Program Files/ImageMagick-6.3.9-Q8”
四 . 解压jmagick-win-6.3.9-Q8.zip
将 jmagick.dll 复制到系统盘下的 “C:/WINDOWS/system32/”文件夹里 和 复制到jdk的bin(例“E:/Java/jdk1.5.0_10/bin”)文件里各一份
将 jmagick.jar 复制到Tomcat下的lib文件夹里 和 所使用项目的WEB-INF下lib文件里 各一份

朋友配的 得自己去网上找资料 :(
