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

将 jmagick.jar 项目lib下

linux

朋友配的 得自己去网上找资料
