Thanks, Chris. I'll have a look at these issues, because during investigations, I found some other strange things. You are right about incorrect Bounding box calculations: Some use a bottom to top Y axis, some other a top to bottom Y axis. This is the explanation of this issue. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
