You can avoid the "Image is locked" errors by having your plugin  
implement PlugIn instead of PlugInFilter. The v1.42l daily build adds  
fillOutside(Roi), Fill(Roi) and draw(Roi) methods to the  
ImageProcessor class. Here is a JavaScript example:

    IJ.run("Clown (14K)");
    IJ.makeOval(91, 41, 151, 108);
    imp = IJ.getImage();
    roi = imp.getRoi();
    ip = imp.getProcessor();
    ip.snapshot();
    ip.setColor(Color.blue);
    ip.setLineWidth(10);
    ip.draw(roi);
    imp.updateAndDraw();
    IJ.wait(2000);
    ip.reset();
    ip.fill(roi);
    imp.updateAndDraw();
    IJ.wait(2000);
    ip.reset();
    ip.fillOutside(roi);
    imp.updateAndDraw();
