At first, we deal with code 39. Code 39 is represented in this package both in form of a native font (Metafont-source) and in form of \TeX{}-macros. code 39 features low-density alphanumeric encoding. Here you may see how HELLO looks like in code 39 (the start and stop sign is mapped to @, if you're curious, so in the source to this sheet I have written {\tt@HELLO@} after having selected the proper font). This first example uses the font. {\xlix@HELLO@} Another approach is to use \TeX{} macros to make up bars. Here is the same HELLO with macros: Please note that for the macro version, you have to use the underbar if you want to have a space coded. \begincodethirtynine{HELLO}\endcodethirtynine Interleaved two-of-five (ITF for short) features high-density numerical-only encoding. Your code has to have an even number of digits. The start sign is mapped to $+$, the end sign to $-$. So, to code 0123456789, you type {\tt+0123456789-}, and the result looks like this: {\itf+0123456789-} If you still have not got enough of barcoding, here is codabar. Here you got four sets of start/stop signs that get decoded together with the numbers. The start/stop sign pairs are a/t, b/n, c/*, and d/e. So {\tt a12345t} looks like this:\bigskip {\cdb a12345t} Now you should have a look at code 128. The bars itself look sometimes disrupted; this is due to the fact that the widest elements are four times as wide as the narrowest. Code 128 enables you to code any 7-bit ascii character. With digits only, it is as efficent as itf. The bad news is the preprocessing required, so you have to read the docs. The following bars mean {\tt Hallo123456}\bigskip \CXXVIII 6828414C4C4F630C2238506A@@ % Code128(Hallo123456) And, last and perhaps most important, the EAN font. Read {\tt eandoc.tex} to find out how these are coded, here is just the output of the example code mentioned there: \embed{2500000000000} \line{ \EAN{4 +AcFHaa-KKLKNK+} % or, without checksum: %(4025700001030) \hfil \EAN{4 +AcFHaa-KKLKNK+} %(402570000103) } \line{ \EAN{2 +FAaaAa-KKLMNT+} % embedded(123) \hfil \EAN{9 +HiaCaB-LNOOSN+} % ISBN(0201134489) } And that's all. Perhaps you may think that this is not a beautiful document---but barcodes aren't beautiful. As long as reading devices do not have \ae{}sthetic feelings, I don't regard this as a problem. \bye \endinput %% %% End of file `examples.tex'.
