coding a contrast stretch.

[Robert Lockwood]

I have a ByteBuffer with an image (16 bits per pixel and monochrome) that I
can display in my UI and I can save as a TIFF file using ImageJ.

I've just written code to read a saved TIFF from a file using ImagePlus,
get the BufferedImage and both display it in my UI and as an ImageJ window.

My test images have absolutely rotten contrast so I need to do a linear
stretch but have not found it in the DOCS yet and Google has been no help.

How do I do this?

TIA

Nate

Probably use the setDisplayRange() method on the ImagePlus before
extracting the AWT Image to display?
