## Meaning of Width for a Control?

[ WIDTH < 1K ]
Suppose I have a control whose width is 10 pixels.

Does this mean there are 10 pixels across the width of the
control (pixels numbered 0 through 9)? In this case, there
is no center pixel.

Or does it mean the control spans a width of 10 pixels
(pixels numbered 0 through 10)? In this case, pixel 5 is in
the center.

A related question is whether there is a center pixel on a
640X480 screen.

At the risk of starting an argument, your thoughts would be
appreciated.

Yes.
You could say there are two center pixels.

That's my thoughts.
I think I'm right, but If I'm not, you can bet that I'll be corrected
very quickly!
