在Ubuntu上安裝ImageMagick和JMagick

1. Install ImageMagick
    sudo apt-get install imagemagick
    2. Install JMagick
    sudo apt-get install libjmagick6-java
    3. Copy jmagick jars to your classpath
    e.g.
    cp /usr/share/java/jmagick*.jar /usr/local/apache-tomcat-5.5.27/common/lib
    4. Copy libJMagick.so to a folder listed in 'java.library.path'
    copy /usr/lib/jni/libJMagick.so /usr/lib/
    /* maybe you should change the permission of the so too */
    sudo chmod 777 /usr/lib/libJMagick.so
    關(guān)于第四個步驟, 是因?yàn)槲以跍y試JMagick的時(shí)候出現(xiàn)了錯誤
    java.lang.UnsatisfiedLinkError: no JMAgick in java.library.path.
    結(jié)果打印了System.getProperty("java.library.path"), 里面有/usr/lib, 而不是/usr/lib/jni.
    所以需要把libJMagick.so復(fù)制到/usr/lib中去.
