2 * stroke.c
3 *
4 * This code uses Zint to encode data in QR Code and then output in
5 * the correct format to use StrokeScribe 2D font. This can be adapted
6 * to encode any matrix symbology using this font.
7 *
8 * The same code can also be used to resolve PDF417 symbols with the
9 * StrokeScribe 417 font and linear symbols with the StrokeScribe 1D
10 * font, all of which are available from the same souce.
11 *
12 * This code can be compiled with:
13 *
14 * gcc -o stroke stroke.c -lzint
15 *
16 * The fonts are available from:
17 *
18 * https://strokescribe.com/en/free-version-barcode-truetype-fonts.html
