> I am attempting to call a PluginFilter from a Plugin.
>
> I call the PluginFilter with
> outfile = tf_back_sub_filename.getText();
> IJ.showMessage(outfile);
> IJ.run("Gradient Subtract Auto", outfile);
>
> The showMessage() verifies that outfile is correct and not empty or null.
>
> The setup function of the PluginFilter is:
>
> public int setup(String arg, ImagePlus imp) {
> this.imp = imp;
> back_filename = arg;
> IJ.showMessage("back_filename is \"" + back_filename + "\"\narg is
> \""+arg+"\"");
> return DOES_32;
> }
>
> However, the showMessage indicates that arg and back_filename are both
> empty.
>
> Is there something I am missing?
