I have moved on from PHP and this project will no longer be updated. If you wish to continue the legacy, please fork the project.
For a maintaned Python implementation check out ihabunek/pdf417-py.

Requires the following components:
- PHP >= 5.4
- PHP extensions: bcmath, fileinfo, gd
Add it to your composer.json file:
composer require bigfish/pdf417
require 'vendor/autoload.php';
use BigFish\PDF417\PDF417;
use BigFish\PDF417\Renderers\ImageRenderer;
use BigFish\PDF417\Renderers\SvgRenderer;
// Text to be encoded into the barcode
$text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur
imperdiet sit amet magna faucibus aliquet. Aenean in velit in mauris imperdiet
scelerisque. Maecenas a auctor erat.';
// Encode the data, returns a BarcodeData object
$pdf417 = new PDF417();
$data = $pdf417->encode($text);
// Create a PNG image
$renderer = new ImageRenderer([
'format' => 'png'
]);
$image = $renderer->render($data);
// Create an SVG representation
$renderer = new SvgRenderer([
'color' => 'black',
]);
$svg = $renderer->render($data);Renders the barcode to an image using Intervention Image
Render function returns an instance of Intervention\Image\Image.
| Option | Default | Description |
|---|---|---|
| format | png | Output format, one of: jpg, png, gif, tif, bmp, data-url |
| quality | 90 | Jpeg encode quality (1-10) |
| scale | 3 | Scale of barcode elements (1-20) |
| ratio | 3 | Height to width ration of barcode elements (1-10) |
| padding | 20 | Padding in pixels (0-50) |
| color | #000000 | Foreground color as a hex code |
| bgColor | #ffffff | Background color as a hex code |
$pdf417 = new PDF417();
$data = $pdf417->encode("My hovercraft is full of eels");
// Create a PNG image, red on green background, extra big
$renderer = new ImageRenderer([
'format' => 'png',
'color' => '#FF0000',
'bgColor' => '#00FF00',
'scale' => 10,
]);
$image = $renderer->render($data);
$image->save('hovercraft.png');The data-url format is not like the others, it returns a base64 encoded PNG
image which can be used in an image src or in CSS. When you create an image
using this format:
$pdf417 = new PDF417();
$data = $pdf417->encode('My nipples explode with delight');
$renderer = new ImageRenderer([
'format' => 'data-url'
]);
$img = $renderer->render($data);You can use it directly in your HTML or CSS code:
<img src="<?= $img->encoded ?>" />And this will be rendered as:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA.... " />Without these pages, implementation of this project would have been much harder:
