Run the Process>Enhance Contrast command with the command recorder
(Plugins>Macros>Record) running and you get this macro call:

      run("Enhance Contrast", "saturated=0.1");

To convert it into a method that can be called from a plugin, change
"run" to "IJ.run" and add an argument that passes an ImagePlus object:

      IJ.run(imp, "Enhance Contrast", "saturated=0.1");
