Mpdf
mPDF ist eine PHP-Bibliothek, die UTF-8-kodiertes HTML und CSS in formatierte PDF-Dokumente umwandelt. Sie dient als PDF-Generierungs-Engine und Dokumentenarchitekt, der in der Lage ist, Webseiten und HTML-Formulare in professionelle Dateien zu konvertieren.
Das Projekt zeichnet sich durch seine mehrsprachigen Rendering-Fähigkeiten aus und bietet umfassende Unterstützung für bidirektionalen Text, Right-to-Left-Skripte und CJK-Sprachen unter Verwendung von Unicode-Schrift-Einbettung und OpenType-Layout-Verarbeitung. Es ermöglicht zudem ein professionelles, druckfertiges Design durch fortschrittliche Farbmodellierung in CMYK, präzise Seitendimensionierung und die Einhaltung von PDF/A- und PDF/X-Archivierungsstandards.
Die Bibliothek deckt eine breite Palette von Dokumentenlayout- und Interaktivitätsfunktionen ab, einschließlich der Generierung interaktiver Formulare, Lesezeichen und durchsuchbarer Indizes. Sie bietet detaillierte Kontrollen für Seitenvorlagen, Kopf- und Fußzeilen sowie komplexes Rendering tabellarischer Daten. Zusätzliche Funktionen umfassen PDF-Verschlüsselung, Schrift-Subsetting zur Optimierung der Dateigröße und die Möglichkeit, externe PDF-Seiten als Vorlagen zu importieren.
Das System integriert sich in PSR-3-konformes Logging, um interne Ereignisse und Ausführungsfehler zu verfolgen.
