Use the command recorder (Plugins>Macro>Record) to generate the needed code. As an example, this is the code generated with the recorder in "Plugin" mode when I opened a grayscale PNG, applied a LUT to it (using File>Import>LUT), and saved it in GIF format.
public class My_Plugin implements PlugIn {
public void run(String arg) {
ImagePlus imp = IJ.openImage("/Users/wayne/test.png");
IJ.run(imp, "LUT... ", "open=/Users/wayne/ImageJ/luts/cool.lut");
IJ.saveAs(imp, "Gif", "/Users/wayne/test.gif");
}
}
