Generate GS1-128 standard barcode

GS1 barcode generator

The library generates GS1 barcode. Currently supported formats: GS1 128., _(*1)

Install

Note that library requires both GD and Free Type extensions installed, _(*2)

composer require ayeo/gs1_barcode:1.0.4

Usage

The simplest example:, _(*3)

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, _(*4)

, _(*5)

Custom barcode:, _(*6)

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., _(*7)

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

If you want to save the image file, you can use the saveImage method instead., _(*8)

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

Both output() and saveImage() methods has additional boolean parameters to determine if label should be included on the print. Default value is true., _(*9)

$builder->output('(10)123456(400)11', $withLabel = false);
$builder->saveImage('(10)123456(400)11', $withLabel = false);

Actually generate the same barcode because all params all set to default values. This shows only available settings, _(*10)

Fluent interface is welcome, _(*11)

use Ayeo\Barcode;

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

Additional info

• Supported image formats: png, jpg
