### 6.4.5 DX Film Edge Barcode
![`zint -b DXFILMEDGE --compliantheight -d
"112-1/10A"`](images/dxfilmedge.svg){.trk}
Introduced by Kodak in the 1980s, the DX (Digital Index) barcode is printed on
the bottom edge of 35mm film to aid in the reordering and post-processing of
prints.
The data can be in two parts. The first part (required) is the "DX number",
identifying the manufacturer and film type - the National Association of
Photographic Manufacturers (NAPM) number. The second part, which is
optional and if present is separated from the first by a slash (`/`), gives the
frame number.
The DX number is in either of two formats. The first format is a number of 1 to
4 digits ("DX Extract") or 6 digits ("DX Full"), but for the 6-digit version the
first and last digit are ignored, leaving a 4-digit DX Extract number in any
case, which must be in the range 16 to 2047. The second format "NNN-NN"
represents the DX Extract as two numbers separated by a dash (`-`), the first
number being 1 to 3 digits (range 1 to 127) and the second 1 to 2 digits (range
0 to 15).[^15]
The optional frame number is a number in the range 0 to 63, and may have a half
frame indicator "A" appended. Special character sequences (with or without a
half frame indicator appended) may also be used: "S" or "X" means frame number
62, "K" or "00" means frame number 63, and "F" means frame number 0.
