Windowing an Image without cloning it

[Johannes Hermen]

Hi,

Does anybody knows a way to "window" an ImagePlus, without creating a new
Image every time?
By now I am do this like that:

------------------------------------------------------------------
Imageplus image;
ImageProcessor imageProcessor;

this.imageProcessor = image.getProcessor();
this.imageProcessor.setMinAndMax(windowMin, windowMax);
this.image = new ImagePlus("ResultImage", this.imageProcessor);
-------------------------------------------------------------------

This way is very CPU and Memory consuming, as I have to copy the image
every time.

Thanks in advance

The Brightness/Contrast and Window/Level tools in ImageJ "window"  
this way:

     ImagePlus imp;
     ImageProcessor ip;

     ip = imp.getProcessor();
     ip.setMinAndMax(windowMin, windowMax);
     imp.updateAndDraw();

The souce code for these tools is at:
