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