In a macro, you can can apply a LUT to a non-visible image by running
the macro in batch mode. Here is an example:

    setBatchMode(true);
    run("Blobs (25K)");
    run("Fire");
    saveAs("Tiff", "/Users/wayne/blobs.tif");

In a plugin, you can do it by using the
WindowManager.setTempCurrentImage() method:

    ImagePlus img = IJ.openImage("/Users/wayne/blobs.tif");
    WindowManager.setTempCurrentImage(img);
    IJ.run("Fire");
    IJ.saveAs("Tiff", "/Users/wayne/blobs2.tif");
