I have a doubt about using TCPDF and FPDI together.
I am working on a project where I need to modify existing PDF file and generate new PDF, actually existing PDF are Greeting card template and I have to print certain data at certain pages (such as Image on first page, message on 3rd page, artwork on 4th page) to generate final PDF.
I googled and found with TCPDF, it is not possible to manipulate existing PDF, they suggested using FPDI for opening and manipulating existing PDF.
That's where i am stuck. I need TCPDF (it methods to print images, transparent images, utf text, embed font etc) to do what I want to do, but, I need FPDI to start with. :(.
Please help me: is it possible to use both FPDI and TCPDF together? so that I can use features offered by both APIs ?
Thanks in advance...

"As of version 1.2.1 FPDI can be used with TCPDF - a derivate of FPDF."
libraries_load('tcpdf');
libraries_load('fpdi');
$pdf = new FPDI();
$pdf->setSourceFile("%local_file_path%");
$tplIdx = $pdf->importPage(1);
$pdf->AddPage('L', array(3.5, 2), FALSE);
$pdf->useTemplate($tplIdx, 0, 0, 3.5, 2, false);
I was using Drupal at the time so I used libraries_load but require_once should work.

I'm creating a web app that allows a canvas form to insert an image from a HTML canvas into a particular position in multiple PDF files. I had this working with python flask as a back-end but the people that I'm making it for only want it in PHP. I have tried using libraries like FPDI but they only work with PDF versions up to 1.4 while the PDF files we are using are version 1.7.
Does anyone know any possible libraries that can help me solve this issue. I would prefer not to convert the PDF files if possible.
Cheers
With TCPDF you can insert images into a PDF (v.1.7) file:
Requirements
composer require tecnickcom/tcpdf
Example
<?php
require_once __DIR__ . '/vendor/autoload.php';
$pdf = new TCPDF();
$pdf->setPDFVersion('1.7');
$pdf->setAutoPageBreak(true);
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
$pdf->AddPage();
// Insert image
$pdf->setJPEGQuality(100);
$pdf->image(__DIR__ . '/example.jpg', 10, 10);
// Close and output PDF document
//$pdf->output('doc.pdf', 'I');
// Save the pdf file
$content = $pdf->output('', 'S');
file_put_contents('example.pdf', $content);
We (Setasign, creator of FPDI) offer a commercial add-on that let you import PDFs which uses a compression technic that was introduced in PDF 1.5.
You may also try to downgrade these documents with an external program. I'm aware of some people using Ghostscript for this.
Generally you should know that you do not insert an image into the existing PDF but you create a completely new PDF while importing a single page into a reusable structure which you place onto a newly created page. On top of this you place the image.
With FPDI you cannot edit a PDF document.
I'm trying to build an header generator for pdf worksheets.
My choice of technologies were:
FPDF and FPDI
Now, I'm transistioning to TCPDF and FPDI, because the powers that be have decided we need water marks (transparencies).
According to the FPDI website, switching is as easy as changing all your require/include statements to say tcpdf.php instead of fpdf.php but in my code below:
//... Code to generate appropriate Graph ...
PDFGenHelper::saveIMG($graph,$imgfilepath);
$filename = "template.pdf";
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile($filename);
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx);
$pdf->Image($imgfilepath, 168, 13, 35, 65);
$pdf->Write(5, "This is just a simple text"); //This line
$pdf->Output($dircache.$userID.'_'.$excerciseID.'_package.pdf', 'F');
Seems to generate an error that says:
Warning: Division by zero in Appropriate directory stuff here/lib/fpdf/fpdf.php on line 819
I've removed all the references to fpdf in my code but it seems to still be coming up with that.
Also, when I try to print to the PDF using the inherited methods from FPDF:
$pdf->SetFont('Arial','B',25);
$pdf->Cell(40,10,'Hello World!');
This will generate text. In addition the FPDI website says FPDI has a Dependency on FPDF_TPL file which looking into the file tells me it extends FPDF.
So to my question: How do you configure FPDI to work with TCPDF instead of FPDF?
If the error is rised in lib/fpdf/fpdf.php then you still have required fpdf.php before TCPDF.
Also: If it's just the transparency you're missing, just use AlphaPDF from the script section.
How can I create a new document using other PDFs that I'm generating?
I have methods to create some documents, and I want to merge them all in a big PDF, how can I do that with TCPDF?
I do not want to use other libs.
TCPDF has a tcpdf_import class, added in 2011, but it is still "under development". If you don't want to use anything outside of TCPDF, you're out of luck!
But FPDI is an excellent addition to TCPDF: it's like an addon. It's as simple as this:
require_once('tcpdf/tcpdf.php');
require_once('fpdi/fpdi.php'); // the addon
// FPDI extends the TCPDF class, so you keep all TCPDF functionality
$pdf = new FPDI();
$pdf->setSourceFile("document.pdf"); // must be pdf version 1.4 or below
// FPDI's importPage returns an object that you can insert with TCPDF's useTemplate
$pdf->useTemplate($pdf->importPage(1));
Done!

Why don't you use Zend_PDF, it 's really a very good way to merge file.
<?php
require_once 'Zend/Pdf.php';
$pdf1 = Zend_Pdf::load("1.pdf");
$pdf2 = Zend_Pdf::load("2.pdf");
foreach ($pdf2->pages as $page){
$pdf1->pages[] = $page;
}
$pdf1->save('3.pdf');
?>
Hi i think TCPDF is not able to merge pdf files.
You can try it with an shell command and
PDFTK Toolkit
So you dont have to use an other pdf library.
This thread is from 2009, but using existing PDFs in PHP is still an issue in 2020.
After Zend_PDF has been abandoned and TCPDI does not support PHP 7, FPDI currently seems one of the few working solutions left in 2020. It can be used with TCPDF and FPDF, so existing code keeps working. And it currently seems well maintained.
Check out FPDI and FPDF_TPL. This isn't a perfect solution, but you can basically use FPDF_TPL to create a template of your PDF file and the insert it into your PDF file.
I have several PDF templates that I would like to load and modify and output using tcpdf.
Is it possible to load an existing PDF and use it as a starting point in tcpdf?
You want to use FPDI.
There's some example code here.
I have tried the free version of FPDI but does not support PDF version 1.5 or higher.
If someone else is looking for a free solution I have used TCPDI. You can find it on github https://github.com/pauln/tcpdi
If you are using composer, you can find some fork for composer too. Just search tcpdi on github.
Once you add it to your project, the code is quite simple. It is an extension of TCPDF so all your previous code keep working
This is a snippet from my code. I used it to save a copy of the privacy policy (a static pdf) with the user name and agreement date on each page footer.
// Create new PDF document
$pdf = new TCPDI(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
...
// Add the pages from the source file.
$pagecount = $pdf->setSourceFile($policyPdfPath);
for ($i = 1; $i <= $pagecount; $i++) {
$tplidx = $pdf->importPage($i);
$pdf->AddPage();
$pdf->useTemplate($tplidx);
// Add agreement text in document footer
$pdf->SetXY(15,282);
$pdf->Cell(180, 5, "Documento approvato da {$fullName} il {$date}", 0, 0, 'C');
}
// Send PDF on output
$pdf->Output(FOLDER_PATH . DIRECTORY_SEPARATOR . "{$userId}.pdf", 'F');
For anyone else finding this, it does appear a PARSER and import class were built for TCPDF (https://tcpdf.org/docs/srcdoc/TCPDF/source-class-TCPDF_IMPORT/#50-100) but as of 2018 was still under development.
Its also worth noting that the solutions above do not allow the contents of the PDF pages to be edited. In other words you import the page as a whole, you cannot edit text content or images.
You can use fpdf with fpdi. You can’t modify directly a template, but you can add a text cell with a white background to cache the old content (note that the old content can be read by using some tools). Then save your new pdf. This tools are relatively easy to use. To resolve the fact that fpdi not read 1.5 pdf version in the free version, you can convert 1.5 version in 1.4 version by using ghost script with the exec command. I use this and work fine.
Background info:
I got a project to produce a customised PDF on the fly from a given PDF file using PHP. All I need it to do is to replace strings, e.g. search in "template.pdf" for "{Address}", replace with "Street Name".
I've seen links to fpdf/pdfi/dompdf etc., but can't find any useful example code that I could use :s.
Any help / pointers would be greatly appreciated.
fpdf is fantastic, you need to use somthing else to import an exisitng PDF though, See below.
http://www.setasign.de/products/pdf-php-solutions/fpdi/
require_once('fpdf.php');
require_once('fpdi.php');
$pdf =& new FPDI();
$pagecount = $pdf->setSourceFile('TestDoc.pdf');
$tplidx = $pdf->importPage(1, '/MediaBox');
$pdf->addPage();
$pdf->useTemplate($tplidx, 10, 10, 90);
$pdf->Output('newpdf.pdf', 'D');
decided to generate html web page (PHP) then use wkhtmltopdf
(http://code.google.com/p/wkhtmltopdf)
to produce the pdf bit of a work around but less hastle
PDFlib (with the additional PDI) from pdflib.com should be able to do this for you. Admittedly it is pretty pricey, so there may be other options, too :)
