What Aztec Runes is
Aztec Runes is a small, fixed-capacity numeric symbol in the same family as the already-covered Aztec Code. bwip-js delegates entirely to its Aztec Code encoder with the format forced to "rune" -- confirmed directly: bwipp_aztecrune declares only a dontdraw option of its own, forces options.format = "rune", and calls bwipp_azteccode().

Enter a number from 0 to 255 to see a live preview.
Valid input
The value must be numeric ("Aztec runes must be numeric") and from 0 to 255 ("Aztec runes must be 0 to 255") -- a small, fixed range, unlike the general-purpose Aztec Code capability this format delegates to.
Key options
Aztec Runes has no useful configurable options beyond the value itself -- confirmed empirically: passing Aztec Code's own eclevel option through to this capability renders a byte-identical symbol either way. This is a fixed-structure micro-symbol with no configurable error-correction level or format choice, unlike the general-purpose Aztec Code encoder it delegates to.

Common uses
Aztec Runes suits small, single-value numeric identifiers (like a ticket class or admission tier) where the general-purpose Aztec Code symbol's larger data capacity is not needed.
Example
See the live preview above, seeded with a bwip-js-verified valid value.
Size guidance
Aztec Runes renders as a small, fixed-structure symbol regardless of the specific 0-255 value chosen -- there is no size control to adjust beyond the standard scale/rotation rendering options.
Troubleshooting
A rejected value is a non-numeric string ("Aztec runes must be numeric") or a number outside 0-255 ("Aztec runes must be 0 to 255").

FAQ
Can Aztec Runes encode text or a longer number?
No -- Aztec Runes only accepts a single numeric value from 0 to 255. For general text or longer data, use the Aztec Code generator instead.
