Vivian,
I also frequently use what one could call a "launcher" class (Dscho's
variant) as the main class to start ImageJ in Eclipse (Galileo), and in
my opinion this route is more convenient than Justin's variant: your
plugin is started automatically, and you can set the launcher to do all
the things a user would normally do before running the plugin. For example:
new ImageJ(null);
IJ.open(path_to_file);
IJ.run("Measure");
IJ.runPlugIn("My_Plugin", "");
The macro recorder in combination with the Convert to Plugin command is
a nice tools to get corresponding java code without having to dig too
much in APIs.//
If you do not want to care about arguments to be passed from the IDE to
the main() method, let the launcher do the job:
import ij.IJ;
import ij.ImageJ;
import java.net.URL;
public class IJLauncher implements Runnable {
public void run() {
String name = getClass().getName();
URL url =getClass().getResource(name+".class");
String path = url.toString().replaceAll("%20", " ");
path = path.substring(6, path.indexOf("/plugins"));
//System.out.println(path);
System.getProperties().setProperty("plugins.dir", path);
new ImageJ(null);
IJ.runPlugIn("My_Plugin", "");
}
public static void main(String args[]) {
Thread runnable = new Thread(new IJLauncher());
runnable.start();
}
}
Yours,
Thomas

It's a little work to set up, but this is the most efficient way I've found to work on ImageJ plugins. You can even attach the ImageJ src to the jar and use those files to debug w/ line references.
