SVGRenderer ​

Raxos\Barcode\Renderer\SVGRenderer renders a barcode matrix to an SVG document. It is the renderer behind Barcode::renderSvg, and can be used directly when you want to reuse a configuration or read its mimeType. Unlike the PNG renderer, it needs no extra PHP extension.

Signature ​

php
final readonly class SVGRenderer extends Renderer implements RendererInterface

It extends the abstract Renderer base class and implements Raxos\Contract\Barcode\RendererInterface.

Properties ​

  • int $scale: the size in pixels of a single module.
  • int $margin: the quiet zone around the barcode in pixels.
  • string $backgroundColor: the background hex color.
  • string $foregroundColor: the dark module hex color.
  • string $mimeType: always image/svg+xml.

Methods ​

__construct ​

php
__construct(
    int $scale = 8,
    int $margin = 16,
    string $backgroundColor = '#ffffff',
    string $foregroundColor = '#000000'
)

Configures the rendering options and sets mimeType to image/svg+xml.

render ​

php
render(BarcodeInterface $barcode): string

Returns a full SVG document string. Horizontal runs of adjacent dark modules are merged into single <rect> elements to keep the markup compact.

Example ​

php
<?php
declare(strict_types=1);

use Raxos\Barcode\PDF417;
use Raxos\Barcode\Renderer\SVGRenderer;

$barcode = new PDF417('RAXOS-0001-EXAMPLE');
$renderer = new SVGRenderer(scale: 4, margin: 8);

$svg = $renderer->render($barcode);
