Hi Ron,

of course, the Macro recorder gives you an answer more easily!

   run("Enhance Contrast", "saturated=0.5");
For a plugin, this simply translates into
   IJ.run("Enhance Contrast", "saturated=0.5");

In contrast to
   new ContrastEnhancer().stretchHistogram(ip, 0.5);
IJ.run works on the foreground image only.
