| The envelope contains no barcode :-) They have: - The strings "Entgeltfrei im Bereich der Deutschen Post" (free shipment in Germany), "Wahlbrief" (postal voting document), "An <address of your local election office>" - The name of the manufacturer and an order number for the envelope (which is identical on all envelopes), "Fachverlag Jüngling-gbb, Bestell-Nr 109 024 9319 099" - Two fields that are filled out by hand (with a pen) by the election office before sending them to the citizen, "Wahlscheinnummer" (serial number) and "Stimmbezirk" (polling station) They have not changed in the last... 30 years? :-) I don't think any of that could trigger a barcode library :-D EDIT: This is not true for all postal voting documents in all German municipalities, every municipality can order their own postal documents from several sources (or even print their own), but the specific envelope with the "green image problem" still does not contain a barcode, as seen in the last image the user posted: https://imgur.com/a/SCHGo4N |
