Hi Jon,

I'm not surprised that you've had difficulty with this issue, as it is not
well-documented in the .Net SDK. The crux of the matter is this: When you
draw a rectangle with a pen, the width of the pen must be taken into
account with regards to the size of the target rectangle. There are 3
basic logical possibilities:

1. The entire line is drawn *inside* the rectangle.
2. The width of the line is split, so that the edge of the rectangle is
centered in the line.
3. The entire line is drawn *outside* the rectangle.

It turns out that number *2* is the method employed with GDI+.

The following is an excellent and detailed article on the subject:

Thanks. I figured it was 2 because the other 2 I tried didn't work. At first
I thought it was a mixture of 1 and 2(the left and top being on the inside
and the bottom and right being on the outside) but none of my calculations
worked and I couldn't find any info regarding it.

Thanks again,
Jon
