barcode | Barcode — A string as scannable barcode geometry: filled faces (one per bar) in the XY plane spanning Width × Height. Symbology picks the STANDARD, not a style — there is exactly one correct rendering per string. Quiet zones are not emitted (a margin is absence of ink): leave clear space around the placement, at least 10 module widths either side. | text | string | 'AIM1234' | The string to encode; single-quote the literal. code128 carries ASCII 32..126 — anything else is an error, never a substitution. |
symbology | string | 'code128' | The barcode standard. 'code128' (ISO/IEC 15417) is the only one implemented. | ||
width | length | 50 | Total symbol width in mm (bars only, no quiet zone). | ||
height | length | 15 | Bar height in mm. |
