QRMarkupSVG

Class QRMarkupSVG: Scalable Vector Graphics (SVG) output.

Example

Set the options:

$options = new QROptions;

$options->version              = 7;
$options->outputInterface      = QRMarkupSVG::class;
// if set to false, the light modules won't be rendered
$options->drawLightModules     = true;
$options->svgUseFillAttributes = true;
// draw the modules as circles isntead of squares
$options->drawCircularModules  = true;
$options->circleRadius         = 0.4;
// connect paths to avoid render glitches
// @see https://github.com/chillerlan/php-qrcode/issues/57
$options->connectPaths         = true;
// keep modules of these types as square
$options->keepAsSquare         = [
	QRMatrix::M_FINDER_DARK,
	QRMatrix::M_FINDER_DOT,
	QRMatrix::M_ALIGNMENT_DARK,
];
// add a gradient via the <defs> element
// @see https://developer.mozilla.org/en-US/docs/Web/SVG/Element/defs
// @see https://developer.mozilla.org/en-US/docs/Web/SVG/Element/linearGradient
$options->svgDefs             = '
	<linearGradient id="rainbow" x1="1" y2="1">
		<stop stop-color="#e2453c" offset="0"/>
		<stop stop-color="#e07e39" offset="0.2"/>
		<stop stop-color="#e5d667" offset="0.4"/>
		<stop stop-color="#51b95b" offset="0.6"/>
		<stop stop-color="#1e72b7" offset="0.8"/>
		<stop stop-color="#6f5ba7" offset="1"/>
	</linearGradient>
	<style><![CDATA[
		.dark{fill: url(#rainbow);}
		.light{fill: #eee;}
	]]></style>';

Render the output:

$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
$out  = (new QRCode($options))->render($data); // -> data:image/svg+xml;base64,PD94bWwgdmVyc2...

printf('<img alt="%s" src="%s" />', $alt, $out);
