BorderCalc

BorderCalc is a simple application that calculates the borders (in inches or centimeters) needed to place a window in the center of a mat or at the so called "optical center". That's all it does.

I've recently updated BorderCalc. The new universal binary version for the Mac works fine on my machine but I haven't had the time or opportunity to try the new Windows version. I've been told the old version worked fine on Windows and I expect the new version also will since the changes were very minor. The application is free, but you download it at your own risk.
