README

The library generates GS1 barcode. Currently supported formats: GS1 128.

Install

Note that library requires both GD and Free Type extensions installed

composer install ayeo/gs1_barcode:1.0.*

Usage

The simplest example:

use Ayeo\Barcode;

$builder = new Barcode\Builder();
$builder->output('(10)123456(400)11');

This will generate png image using black and white and default font

Custom barcode:

use Ayeo\Barcode;

$builder = new Barcode\Builder();
$builder->setBarcodeType('gs1-128');
$builder->setFilename('barcode.png');
$builder->setImageFormat('png');
$builder->setWidth(500);
$builder->setHeight(150);
$builder->setFontPath('FreeSans.ttf');
$builder->setFontSize(15);
$builder->setBackgroundColor(255, 255, 255);
$builder->setPaintColor(0, 0, 0);

Finally, you can use the output method to stream the image directly to the web browser.

$builder->output('(10)123456(400)11');

If you want to save the image file, you can use the saveImage method instead.

$builder->saveImage('(10)123456(400)11');

Acctualy generate the dame barcode becouse all params all set to default values. This shows only available settings

Fluent interface is welcome

use Ayeo\Barcode;

Barcode\Builder::build()->setWidth(600)->setBackgroundColor(100, 100, 100)->output('(10)123456(400)11');

Additional info
