Hi Seth, I committed you patch, because it displays a warning message about the %FSD incorrect format statement (previously this warning message was missing in Gerbview), and the %FSD was already existing in Gerbview, but perhaps incorrectly handled (who knows, %FSD was never documented in the official Gerber doc). Thanks for your contribution. -- 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
