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

Note that library requires both GD and Free Type extensions installed

composer require ayeo/gs1_barcode:1.0.4

The simplest example:

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

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

Custom barcode:

useAyeo\Barcode;$builder =newBarcode\Builder();$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');

Both output() and saveImage() methods has additional boolean parameters to determine if label should be included onthe print. Default value is true.

$builder->output('(10)123456(400)11',$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 onlyavailable settings

Fluent interface is welcome

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

• Supported image formats: png, jpg
• Barcode must be valid GS1 barcode
