I've been working on a small application that allows selection of an ROI
from an original 16 bit unsigned TIFF image and writing the original
("backing ") data in the ROI as a CSV file. I'm displaying the image using
a JImagePanel. This will be used to examine pixels of interest such as to
determine if some pixels are stuck on, stuck off, noise, dust, or a defect
in a vendor supplied calibration file.
It's difficult to use the cursor to pick out an individual pixel so I'd
like to be able to display an area around the cursor magnified. I'm not
particular about how this is accomplished but don't want the window as yet
another component within my application's JFrame. I'm working in Ubuntu
LINUX and have a utility "KMag" that illustrates kind of what I'm looking
for but a separate utility won't work for my users who will be using other
operating systems.
Can I "grab" the data under, say, a 10x10 pixel ROI centered on the cursor
and display it in , say, a 20x20 or 40x40 pixel window with magnification?
It would need to update as the cursor is moved, of course.

So far, so good.
