the 2of5 font is a barcode font encoding the interleaved 2of5 barcode standard.
The font is available in 5 different height to width ratios. (Usually i use code39_XL)
if you need other height to width ratios, you can generate your own font using the barcode font generator
| name | height to width ratio | font size to get 1px wide bars |
|---|---|---|
| 2of5_S | 1:1 | 14px |
| 2of5 | 2:1 | 28px |
| 2of5_L | 3:1 | 42px |
| 2of5_XL | 4:1 | 56px |
| 2of5_XXL | 5:1 | 70px |
You can download the font in .ttf, .woff, and .svg format.
You can install it as any other font. To use it as a webfont, you can install with bower:
bower install --save code-39-font
and the in your .html:
<link rel="stylesheet" href="bower_components/code-39-font/code39_all.css"/>
<div class="code_39_XL">*Test*</div>
an explicit encoding is not necessary. To create a barcode. Simply write your string to be encoded with this font.
2of5 can only encode digits 0-9 and only an even number of digits. The standard does not specify a mapping of the start and stop symbols to a certain ascii code. So i made the mapping up myself. The start code is : and the stop code is ;
so to encode the sequence 123456 just write :123456; and print it with the 2of5 font.
