QRFpdf

Class QRFpdf: Portable Document Format (PDF) output via FPDF

Example

See: FPDF example

Set the options:

$options = new QROptions;

$options->outputInterface  = QRFpdf::class;
$options->scale            = 5;
$options->fpdfMeasureUnit  = 'mm'; // pt, mm, cm, in
$options->bgColor          = [222, 222, 222]; // [R, G, B]
$options->drawLightModules = false;
$options->moduleValues     = [
	QRMatrix::M_FINDER_DARK    => [0, 63, 255],    // dark (true)
	QRMatrix::M_FINDER_DOT     => [0, 63, 255],    // finder dot, dark (true)
	QRMatrix::M_FINDER         => [255, 255, 255], // light (false)
	QRMatrix::M_ALIGNMENT_DARK => [255, 0, 255],
	QRMatrix::M_ALIGNMENT      => [255, 255, 255],
	QRMatrix::M_DATA_DARK      => [0, 0, 0],
	QRMatrix::M_DATA           => [255, 255, 255],
];

Render the output:

$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
$out  = (new QRCode($options))->render($data); // -> data:application/pdf;base64,...

echo $out;

Return the FPDF instance (will ignore other output options):

$options->returnResource = true;

/** @var \FPDF $fpdf */
$fpdf = (new QRCode($options))->render($data);

// do stuff with the FPDF instance...

// ...dump output
header('application/pdf');

echo $fpdf->Output('S');
