Well, look. I doubt you have a display that can accommodate
an image that has a 10000 in one of its dimensions, so you
are going to change the "state" of the data no matter what
you do. And don't make the mistake of confusing your data
with the *display* of the data. They are two completely
different things. For one thing, it is doubtful whether
your data is in the range of 0 to 255, the only kind of
"data" that can be displayed on the computer.

Depends on how much money you have in your programming budget
for contractors. :-)
