GS1 DataMatrix

Kind	Charset	Capacity	URL	Phone
2D matrix	GS1 AI data	AI `01`, `10`, `17`, `21`, single-region	No	No

GS1 DataMatrix uses the same GS1 input contract as Gs1128, then renders an ECC200-style Data Matrix with the initial FNC1 codeword.

Example

Gs1DataMatrix::create('(01)09501101530003(17)260728(10)BATCH42')->render();

Usage

use Atelier\Barcode\Gs1DataMatrix;

echo Gs1DataMatrix::create([
    ['01', '09501101530003'],
    ['17', '260728'],
    ['10', 'BATCH42'],
])
    ->size(220)
    ->margin(2)
    ->render();

Options

Method	Default	Description
`size(int)`	`220`	SVG width and height in pixels
`margin(int)`	`2`	quiet zone, in modules
`foreground(string)`	`#000000`	module color
`background(string)`	`#ffffff`	background color

matrix() returns the raw module grid. payload() returns the encoded GS1 payload and elementString() returns the printable (AI)value form.

The same symbol carrying only (01). Each application identifier you drop shrinks the grid, because the element string is what gets encoded.

Limits

Supported AIs: 01 GTIN, 17 expiry date, 10 batch/lot, 21 serial.
Single-region square Data Matrix symbols only, from 10x10 to 26x26.
Throws when the resulting GS1 payload no longer fits that range.
