Re: How to center a circle?

Hello Ralf,

Select any of
 https://www.google.com/search?q=public+upload+site
?

this was very helpful. The screen shots are now on https://imgbb.com/
with the URLs:
TkPath: https://ibb.co/gg6XsRm
Tk:     https://ibb.co/LkGg9mv
Apart from the rugged edge in Tk they look pretty identical to me.
And to me the left and top edges are significant smaller than their
right and bottom counter parts - about less than half I would say.

Am I crazy? Does my monitor play tricks with me? I know that I don't
have perfect eye sight - that's why I am wearing glasses since the age
of ten and so far it has helped me lead a normal life.

A very confused
Helmut
