The encoding rules for Code39 code are:
1. Each five lines represent a character;
2. Thick line represents 1, thin line represents 0;
3. The wide gap between lines indicates 1, and the narrowest one indicates 0;
4. Five lines plus the four gaps between them are nine-digit binary codes, and three of these nine digits must be 1, so it is called 39 codes;
5. One * marks the beginning and end of the barcode.
