Code 128

Kind Charset Capacity URL Phone
1D linear 7-bit ASCII Unbounded* Yes Yes

Dense linear barcode over the full 7-bit ASCII range. Automatically picks code sets to keep numeric runs compact, and always appends its own checksum.

Example

ATELIER-2026 
Code128::create('CODE-128')->render();

Usage

use Atelier\Barcode\Code128;

echo Code128::create('SHIP-4417-XZ')
    ->scale(2)
    ->height(80)
    ->withText(false)
    ->foreground('#08090c')
    ->background('#f4f0e8')
    ->render();

Options

Method Default Description
scale(int) 2 pixels per module
height(int) 80 bar height in pixels
margin(int) 10 quiet zone, in modules
foreground(string) #000000 bar color
background(string) #ffffff background color
withText(bool) true show the human-readable value under the bars

modules() returns the raw bar pattern instead of SVG.

Fourteen digits in a narrower symbol than the twelve-character value above. Code set C packs two digits per symbol, and the encoder switches to it on its own.

Limits

  • Any byte above 127 throws InvalidCodeException (Code 128 supports 7-bit ASCII only).
  • Empty data throws.
  • No maximum length enforced by this library; very long data produces a wide barcode.

Unbounded = no hard cap in this implementation; physical/print width is the real constraint.
