The default templates then print the slip at the bottom of a page of its own instead of the small code next to the bank details. - [`QrImage`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Qr/QrImage)Renders QR codes as SVG data URIs for templates (no further dependency besides mpdf/qrcode). ### [Quittio\\Core\\Pdf\\Renderers](https://quittio.dev/docs/api/Quittio/Core/Pdf/Renderers) - [`CallbackRenderer`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Renderers/CallbackRenderer)Own rendering function (e.g. Browsershot, Gotenberg) that returns PDF binary data. PDF/A and the embedded XML are added by the post processor. - [`DenyingHttpClient`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Renderers/DenyingHttpClient)mPDF HTTP client that refuses every request (defence in depth). - [`MpdfRenderer`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Renderers/MpdfRenderer)Default renderer: HTML/CSS to PDF/A-3b with mPDF, in pure PHP. - [`PassthroughRenderer`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Renderers/PassthroughRenderer)Uses a finished PDF supplied by the application; only PDF/A and the XML are added. ### [Quittio\\Core\\Pdf\\Xmp](https://quittio.dev/docs/api/Quittio/Core/Pdf/Xmp) - [`FacturXXmp`](https://quittio.dev/docs/api/Quittio/Core/Pdf/Xmp/FacturXXmp)XMP metadata for Factur-X/ZUGFeRD: the fx description and the PDF/A extension schema. Without the extension schema the PDF is readable, but not valid PDF/A. ```json {"@context":"https://schema.org","@graph":[{"@id":"https://quittio.dev/#website","@type":"WebSite","description":"E-Rechnungen für PHP und Laravel: ZUGFeRD, XRechnung und Peppol erstellen, prüfen, lesen und archivieren.","inLanguage":"de-DE","name":"Quittio","url":"https://quittio.dev/","publisher":{"@id":"https://quittio.dev/#identity"},"workTranslation":{"@id":"https://quittio.dev/en#website"}},{"@id":"https://quittio.dev/docs/api/Quittio/Core/Pdf#webpage","@type":"WebPage","description":"The public classes in Quittio\\Core\\Pdf.","name":"Quittio\\Core\\Pdf – API-Referenz","url":"https://quittio.dev/docs/api/Quittio/Core/Pdf","isPartOf":{"@id":"https://quittio.dev/#website"},"potentialAction":[{"@type":"ReadAction","target":["https://quittio.dev/docs/api/Quittio/Core/Pdf"]}],"primaryImageOfPage":{"@id":"https://quittio.dev/#logo"}},{"@id":"https://quittio.dev/#identity","@type":"Organization","description":"Open-Source-Bibliothek für E-Rechnungen in PHP und Laravel (ZUGFeRD, XRechnung, Peppol) und Quittio Managed.","email":"kontakt@niklasforst.de","legalName":"Niklas Forst – Softwareentwicklung","name":"Quittio","url":"https://quittio.dev","founder":{"@type":"Person","name":"Niklas Forst","url":"https://quittio.dev/ueber"},"logo":{"@id":"https://quittio.dev/#logo"},"sameAs":["https://github.com/Quittio/quittio","https://packagist.org/packages/quittio/quittio"]},{"@id":"https://quittio.dev/#logo","@type":"ImageObject","caption":"Quittio","contentUrl":"https://quittio.dev/logo.png","inLanguage":"de-DE","url":"https://quittio.dev/logo.png"}]} ```
