Hi there,
I modified the BackgroundSubtracter class by adding one method:
        public void setWhiteBackground(boolean b) { whiteBackground = b; }
and delete: package ij.plugin.filter; changed its name to BackgroundSubtracterM.java; Then I saved to plugin folder.

I used in a plugin as:
            BackgroundSubtracterM bgs = new BackgroundSubtracterM();
            bgs.setWhiteBackground(false);
            bgs.subtractBackround(ip, 50);


D:\Program Files\ImageJ\plugins\ALM\BackgroundSubtracterM.java:23: Interface PlugInFilter of class BackgroundSubtracterM not found.
public class BackgroundSubtracterM implements PlugInFilter {

But it does not happen if  I use the  original  class:
            BackgroundSubtracter bgs = new BackgroundSubtracter();
             ///bgs.setWhiteBackground(false);
             bgs.subtractBackround(ip, 50);

What is wrong with my modification?
Thanks.
Bian
