Tfpdf Laravel Package

Getting Started

• Install via Composer: composer require setasign/tfpdf. This package is a drop-in replacement for FPDF with UTF-8 support.
• Start by extending \setasign\Tfpdf\Tfpdf instead of FPDF in your PDF-generating classes.
• For basic usage, instantiate the class, set font (must be a TTF font), add a page, and output:

  $pdf = new \setasign\Tfpdf\Tfpdf();
  $pdf->AddFont('DejaVu', '', 'DejaVuSans.ttf', true);
  $pdf->AddPage();
  $pdf->SetFont('DejaVu', '', 12);
  $pdf->Write(0, 'Hello, 世界 🌍');
  $pdf->Output();
  

• First place to look: check the examples/ directory in the repo and examples/font/ for TTF setup instructions.
• Primary use case: generating multilingual PDFs (e.g., Arabic, Cyrillic, CJK via fallback, though limited) without external dependencies.

Implementation Patterns

• Font Registration: Use AddFont() with the 4th parameter set to true to register UTF-8-capable TrueType fonts. Fonts must reside in the fonts/ directory (usually vendor/setasign/tfpdf/fonts/ or custom path via setFontLocation()).
• Custom Font Paths: Override the default font directory with Tfpdf::setFontLocation($path) before calling AddFont().
• Integration with Laravel:
  • Create a service provider or helper that initializes a configured Tfpdf instance (e.g., preloading DejaVu fonts).
  • Use in console commands or jobs where PDFs are generated without web output (use Output('pdf.pdf', 'F')).
• Styling & Layout: Use same FPDF methods (Cell, MultiCell, SetXY)—UTF-8 only affects text encoding, not layout.
• Fallback Strategy: Since full CJK isn’t supported out-of-the-box, combine with SetFont(' DejaVu'...) for basic Latin + diacritics, and consider multicell for line-breaking text.

Gotchas and Tips

• No True CJK Support: Tfpdf supports UTF-8 byte sequences, but rendering depends on font coverage. DejaVu Sans covers most Latin, Cyrillic, Greek, and basic Arabic—but not Chinese/Japanese/Korean fully. For full CJK, consider TCPDF or dompdf instead.
• Font Loading Path Issues: The AddFont() method expects fonts relative to the fonts/ directory unless setFontLocation() is called. Common error: font not found due to incorrect path—use absolute paths.
• Empty Output on CLI: In console environments, ensure output_buffering = Off and zlib.output_compression = Off in php.ini. Tfpdf may silently fail to output if headers have already been sent.
• Debugging Font Rendering: Use Tfpdf::getError() after AddFont() or SetFont() to check for issues.
• Compatibility: This is not PSR-0/PSR-4 compatible by default; ensure autoloading via Composer is configured correctly. Avoid manual require_once statements.
• No Active Maintenance: Last release in 2022—verify license compatibility (LGPL) and consider forking for critical security updates if needed.
• Extension Tip: To add custom content (e.g., barcodes, shapes), extend Tfpdf and override Header(), Footer(), or add custom methods.
