Raw bar-width prototyping at a taller bar height

When prototyping or visually reviewing a custom bar-width pattern, a taller bar height can make the individual widths easier to inspect -- this generator applies a fixed, taller height by default.

Same generator, one preset applied

This experience uses the same raw capability as the primary generator, with a fixed 20mm bar height ("height": 20) instead of the primary's own 12.5mm example value.

Example data

The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.

Workflow

Enter your digit-only bar-width pattern, confirm the preview, then export SVG or PNG.

Job-specific settings

No job-specific options beyond the fixed 20mm bar height are applied here.

Scanning notes

This is a diagnostic/prototyping tool, not a symbology any standard barcode reader is configured to decode.

Common mistakes

Entering "0" or a non-digit character is the most common rejection; this is unaffected by the height preset itself.

Standard

This is a bwip-js/BWIPP-specific diagnostic primitive, not a standards-body-defined symbology.
