DAFT with a taller bar height for printed alignment charts
A taller bar height makes the four distinct bar states easier to compare visually on a printed alignment or calibration chart -- this generator applies a fixed, taller bar height by default.
Same generator, one preset applied
This experience uses the same DAFT capability as the primary generator, with a fixed 30mm bar height ("height": 30) instead of bwip-js's own literal 0.175in default.
Example data
The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.
Workflow
Enter a D/A/F/T value, confirm the preview, then export SVG or PNG for the printed chart.
Job-specific settings
No job-specific options beyond the fixed 30mm bar height are applied here.
Scanning notes
DAFT has no reader/decoder convention of its own -- it is a visualization tool, not a barcode meant to be scanned as a business identifier.
Common mistakes
A character other than D, A, F, or T (including lowercase letters) is the most common rejection; this is unaffected by the taller-height preset itself.
Standard
DAFT visualizes the 4-state bar mechanism ("Custom 4 state symbology," per bwip-js's own listing) shared by real postal symbologies such as Australia Post and Royal Mail.
