Size from two Point variables

[Dan Reber]

I have to Point variables that are being set on MouseDown and MouseUp
events --

mousedownPoint = new Point(e.X, e.Y);
mouseupPoint = new Point(e.X, e.Y);

Is there a way that I can take those two points and get a Height and Width
value from it to use for a Size variable? I have tried many different ways
but none of them have worked.

Thanks

Dan

You can convert the points to sizes and then use Size subtraction, but
have to deal with issues like did they drag from top/left to
bottom/right or reverse.

I think easiest is to just perform math separately and then create a
size structure from that:

height = Math.Abs(mousedownPoint.X - mouseupPoint.X);
width = Math.Abs(mousedownPoint.Y - mouseupPoint.Y);

Size sz = new Size(width, height);

Unless you want the sizes to be negative which is possible depending
on what you're going to do with the data...

HTH,
