How to auto-adjust brightness/contrast from a plugin?

[DwightBart]

Under the "Image" menu there is the "Adjust" submenu from which you can
choose "Brightness/Contrast".  From the Brightness/Contrast window you
can click the "Auto" button.

 

Okay, say within a plugin I've just created an image.  Before I display
this image I want to perform this auto-brightness/contrast adjustment.
Is there an easy way to do this?

 

Sincerely,

Dwight Bartholomew

Here is one way

     new ContrastEnhancer().stretchHistogram(ip, 0.5);

where ip is an ImageProcessor. Or display the image and run the  
Process>Enhance Contrast command using

     IJ.run("Enhance Contrast", "saturated=0.5");

In a macro, use

     run("Enhance Contrast", "saturated=0.5");
