Writing the entry point

This might for example be an ImageJ plugin. This is also simple and straightforward:

public class Main implements PlugInFilter {

	private ImagePlus image;

	@Override
	public int setup(String arg, ImagePlus imp) {
		this.image = imp;
		return DOES_ALL;
	}

	@Override
	public void run(ImageProcessor ip) {
		run(image);
	}

	public static void run(ImagePlus image) {
		ExtRenderer renderer = new ExtRenderer(image);
		AnimationEditor editor = new AnimationEditor(
						renderer, null);
		editor.setVisible(true);
	}
}
