ImageJ二次开发学习纪录之初步体会

ImageJ的相关信息可以直接从其官网了解,从这个网站上可以下载到其运行程序，并可以得到相关的源码，在源码的基本上我们可以进行插件开发。

1）了解插件的类型及其接口：

　　 a) PlugIn:启动该插件时不需要打开一幅图象
　　 b) PlugInFilter:启动该插件时,需要传递给该插件一幅打开图象的指针。该插件的操作将施加在该图象上。
　　 c) PlugInFrame:该插件可以扩展一个独立的操作交互界面。

2)相关程序的运行方式，只要将相关的插件的.java和.class放在源码目录source/plugins下就可以了，可以使用再往下一级的目录进行存放，然后重新编译运行整个ImageJ源码就可以了，它会自己识别source/plugins下的插件，并将插件显示在运行后的程序的Plugins栏目下；

3）为了便于在同一个目录下进行编译和运行，使用了如下的build.xml（引用了整体程序的build.xml),plugins下使用一级目录

source/build.xml
