CODE 128

CODE 128 covers the full ASCII set across three subsets: A for control characters and upper case, B for the printable range including lower case, C for pairs of digits at one character per two. This type picks the subsets and the switches between them from the payload, which for numeric data means roughly half the width of CODE 39.

Where the subset has to be fixed, use C128A, C128B or C128C instead.

Digits, which switch the encoder into subset C

<?php

require_once __DIR__ . '/vendor/autoload.php';

$barcode = new \Com\Tecnick\Barcode\Barcode();
$bobj = $barcode->getBarcodeObj(
    type: 'C128',
    code: '0123456789',
    width: -3,
    height: -30,
    color: 'black',
    padding: [0, 0, 0, 0],
)->setBackgroundColor('white');

echo $bobj->getInlineSvgCode();

Mixed case text

$bobj = $barcode->getBarcodeObj(
    type: 'C128',
    code: 'tc-lib-barcode',
    width: -3,
    height: -30,
    color: 'black',
    padding: [0, 0, 0, 0],
)->setBackgroundColor('white');
