Exporting QR code from CMD or application to EMF format a border is added, even though Border Type = No order and Border Width = 0 X.
Border appears if imported to Word 356 or opened with Paint.
Generally, opening EMF in Inkscape and removing the white background solves it.
Maybe, the border is added by Word/Paint ? Are you aware of the no background option ?
Indeed, nobackground has done the trick.
Thanks
