[Gimp-user] How to round all square corners?

[helices <helices helices org>]

Hi!

Suppose we have a standard QR code composed of hundreds of squares and 
their hundreds of square corners. (e.g., 
http://en.wikipedia.org/wiki/QR_code)

How can I get Gimp to round all of the internal and external square 
corners - let's say to a 10 pixel radius?

Thank you.

If ever I can be of service to you, contact me at once.

I hope that you have a truly extraordinary day ...
