TCPDF - generate PDF documents with PHP

TCPDF is a PHP library for the programmatic generation of PDF documents, allowing developers to create files containing text, graphics, and forms directly from application code. It includes a typography engine that supports Unicode strings, bidirectional scripts, and the embedding of TrueType or OpenType fonts.

The library provides specialized tools for producing documents that adhere to PDF/A, PDF/X, and PDF/UA standards for archiving, printing, and accessibility. It features a digital signing system that applies CMS signatures and RFC 3161 timestamps, supporting long-term validation through OCSP responses and CRL payloads. Additionally, it includes a barcode generator for embedding 1D and 2D formats, such as QR codes and DataMatrix, into documents.

The project covers broad capability areas including color space management across RGB, CMYK, and HSL models, and the ability to import and parse existing PDF pages. It implements security controls via allowlists to restrict local file paths and remote hostnames during asset loading. Performance is managed through font subsetting to reduce file size and backend caching for processed images and fonts.

Features

PDF Document Generation - Produces PDF files containing text, graphics, signatures, and forms directly from PHP application code.
Unicode Typography Renderers - Implements a typography renderer using Unicode and OpenType support to produce high-quality digital documents.
Document Signing Implementations - Implements cryptographic digital signatures to verify the authenticity and integrity of PDF documents.
PDF Generation Libraries - Provides a comprehensive PHP library for the high-level construction and formatting of professional PDF documents.
PDF Object Composition - Builds documents by organizing text, graphics, and signatures as distinct internal objects within the PDF structure.
Text Typography Controls - Handles Unicode strings, bidirectional text, and custom font subsetting to support diverse languages and scripts.
PDF Security and Signing - Applies CMS signatures and RFC 3161 timestamps to ensure PDF document authenticity.
Digital Signatures - Integrates detached CMS signatures and TSA timestamps to guarantee document integrity.
Coordinate-Based Layouts - Positions document elements using an absolute coordinate system based on defined units of measurement.
Multilingual Typography Systems - Provides a typography engine that handles Unicode strings and bidirectional scripts for diverse international languages.
PDF Font Embedding - Embeds TrueType and OpenType font formats into PDF files to ensure consistent cross-platform rendering.
PDF Page Embedding - Embeds pages from existing PDF documents as objects to be placed onto new destination pages.
PDF Archival Standard Compliance - Ensures documents adhere to PDF/A, PDF/X, and PDF/UA standards for long-term archiving and accessibility.
PDF Document Importers - Parses external PDF files to extract and place existing pages into new documents.
Color Modeling Systems - Manages color definitions and conversions across RGB, CMYK, HSL, and Lab models for consistent print output.
Barcode Generators - Generates various 1D and 2D barcode formats, including QR codes and DataMatrix, for embedding in documents.
PDF Barcode Embedding - Includes a barcode generator for embedding 1D and 2D formats like QR codes and DataMatrix into PDFs.
Long Term Validation - Includes OCSP responses and CRL payloads within the document to support offline signature verification.
CMS Signature Integration - Integrates detached CMS signatures and RFC 3161 timestamps to ensure document integrity and authenticity.
Color Management Systems - Converts colors across RGB, CMYK, HSL, and spot color systems to ensure consistent visual output.
Font Subsetting Engines - Minimizes embedded font file size by extracting only the specific glyphs used in the document.
