## NOTE
|
||||
A new version of this library is under development at https://github.com/tecnickcom/tc-lib-pdf and as a consequence this library is in support only mode.
|
||||
## Deprecation Notice
|
||||
|
||||
TCPDF is **deprecated** and in **maintenance-only mode**.
|
||||
|
||||
Active feature development has moved to [tc-lib-pdf](https://github.com/tecnickcom/tc-lib-pdf), the modern and modular successor.
|
||||
|
||||
## Description
|
||||
For new projects, use `tecnickcom/tc-lib-pdf`. This repository remains available for legacy systems and critical compatibility fixes.
|
||||
|
||||

|
||||
- New projects: install `tecnickcom/tc-lib-pdf`.
|
||||
- Existing TCPDF users: keep TCPDF for current production workloads and migrate in phases.
|
||||
- Teams seeking modern architecture, Composer-first design, and stronger type-safety should prioritize `tc-lib-pdf`.
|
||||
|
||||
### Third party fonts:
|
||||
### Why Migrate to tc-lib-pdf
|
||||
|
||||
This library may include third party font files released with different licenses.
|
||||
- Modern architecture: modular libraries and cleaner component boundaries improve maintainability.
|
||||
- Better extensibility: new features are easier to add without patching a monolithic legacy core.
|
||||
- Stronger tooling fit: modern package structure works better with static analysis, CI, and automated tests.
|
||||
- Lower long-term risk: reduces technical debt tied to legacy APIs and supports ongoing PHP ecosystem evolution.
|
||||
- Improved delivery speed: teams can implement and ship new PDF capabilities with less friction.
|
||||
|
||||
All the PHP files on the fonts directory are subject to the general TCPDF license (GNU-LGPLv3),
|
||||
they do not contain any binary data but just a description of the general properties of a particular font.
|
||||
These files can be also generated on the fly using the font utilities and TCPDF methods.
|
||||
Migration still requires planning and regression checks to preserve rendering parity for existing documents.
|
||||
|
||||
All the original binary TTF font files have been renamed for compatibility with TCPDF and compressed using the gzcompress PHP function that uses the ZLIB data format (.z files).
|
||||
### Future Compatibility Possibility
|
||||
|
||||
The binary files (.z) that begins with the prefix "free" have been extracted from the GNU FreeFont collection (GNU-GPLv3).
|
||||
The binary files (.z) that begins with the prefix "pdfa" have been derived from the GNU FreeFont, so they are subject to the same license.
|
||||
For the details of Copyright, License and other information, please check the files inside the directory fonts/freefont-20120503
|
||||
Link : https://www.gnu.org/software/freefont/
|
||||
As a long-term possibility, TCPDF could be refactored to use `tc-lib-pdf` internally as a backend while preserving a practical level of backward compatibility for existing TCPDF integrations.
|
||||
|
||||
The binary files (.z) that begins with the prefix "dejavu" have been extracted from the DejaVu fonts 2.33 (Bitstream) collection.
|
||||
For the details of Copyright, License and other information, please check the files inside the directory fonts/dejavu-fonts-ttf-2.33
|
||||
Link : http://dejavu-fonts.org
|
||||
This is not part of a committed roadmap and there is no guarantee it will happen. It is documented here only as a potential direction that may be evaluated in the future.
|
||||
|
||||
The binary files (.z) that begins with the prefix "ae" have been extracted from the Arabeyes.org collection (GNU-GPLv2).
|
||||

### ICC profile:
|
||||
## Overview
|
||||
|
||||
TCPDF includes the sRGB.icc profile from the icc-profiles-free Debian package:
|
||||
https://packages.debian.org/source/stable/icc-profiles-free
|
||||
TCPDF is a pure-PHP library for generating PDF documents and barcodes directly in application code.
|
||||
|
||||
It has been widely used across many PHP stacks and still provides a complete feature set for text rendering, page composition, graphics, signatures, forms, and standards-oriented output.
