1 /*
2 * daft.c
3 *
4 * This code uses Zint to encode data into a USPS Intelligent
5 * Mail symbol, and then converts the output to "DAFT code"
6 * which is used by commercial fonts to display this and
7 * similar 4-state symbologies.
8 *
9 * This code can be compiled with:
10 *
11 * gcc -o daft daft.c -lzint
12 *
13 * The output characters are:
14 *
15 * D = Descender
16 * A = Ascender
17 * F = Full
18 * T = Tracker
19 *
