❗ This document refers to FPDI 2. Version 1 is deprecated and development is discontinued. ❗

FPDI is a collection of PHP classes facilitating developers to read pages from existing PDF documents and use them as templates in FPDF, which was developed by Olivier Plathey. Apart from a copy of FPDF, FPDI does not require any special PHP extensions.

FPDI can also be used as an extension for TCPDF, too.

Because FPDI can be used with FPDF or TCPDF we didn't added a fixed dependency in the main composer.json file but we added metadata packages for both FPDF and TCPDF.

For FPDF add following package to your composer.json:

{
    "require": {
        "setasign/fpdi-fpdf": "^2.0"
    }
}

For TCPDF add following package to your composer.json:

{
    "require": {
        "setasign/fpdi-tcpdf": "^2.0"
    }
}

If you don't want to use the metadata packages, it is up to you to add the dependencies to your composer.json file.

To use FPDI with FPDF include following in your composer.json file:

{
    "require": {
        "setasign/fpdf": "^1.8",
        "setasign/fpdi": "^2.0"
    }
}

If you want to use TCPDF, your have to update your composer.json respectively to:

{
    "require": {
        "tecnickcom/tcpdf": "^6.2",
        "setasign/fpdi": "^2.0"
    }
}

If you do not use composer, just require the autoload.php in the /src folder:

require_once('src/autoload.php');

If you have a PSR-4 autoloader implemented, just register the src path as follows:

$loader = new \Example\Psr4AutoloaderClass;
$loader->register();
$loader->addNamespace('setasign\Fpdi', 'path/to/src/');

Version 2 is a complete rewrite from scratch of FPDI which comes with:

• Namespaced code
• Clean and up-to-date code base and style
• PSR-4 compatible autoloading
• Performance improvements by up to 100%
• Less memory consumption
• Native support for reading PDFs from strings or stream-resources
• Support for documents with "invalid" data before their file-header
• Optimized page tree resolving
• Usage of individual exceptions
• Several test types (unit, functional and visual tests)

We tried to keep the main methods and logical workflow the same as in version 1 but please notice that there were incompatible changes which you should consider when updating to version 2:

• You need to load the code using the src/autoload.php file instead of classes/FPDI.php.
• The classes and traits are namespaced now: setasign\Fpdi
• Page boundaries beginning with a slash, such as /MediaBox, are not supported anymore. Remove the slash or use a constant of PdfReader\PageBoundaries.
• The parameters $x, $y, $width and $height of the useTemplate() or getTemplateSize() method have more logical correct default values now. Passing 0 as width or height will result in an InvalidArgumentException now.
• The return value of getTemplateSize() had changed to an array with more speaking keys and reusability: Use width instead of w and height instead of h.
• If you want to use FPDI with TCPDF you need to refactor your code to use the class TcpdfFpdi instead of FPDI.

A simple example, that imports a single page and places this onto a new created page:

<?php
use setasign\Fpdi;

// setup the autoload function
require_once('vendor/autoload.php');

// initiate FPDI
$pdf = new Fpdi\Fpdi();
// add a page
$pdf->AddPage();
// set the source file
$pdf->setSourceFile("Fantastic-Speaker.pdf");
// import page 1
$tplId = $pdf->importPage(1);
// use the imported page and place it at point 10,10 with a width of 100 mm
$pdf->useTemplate($tplId, 10, 10, 100);

$pdf->Output();
