TCPDF is an open-source PHP library and the only PHP-based library that includes complete support for UTF-8 Unicode and right-to-left languages, including the bidirectional algorithm.
In this article, we will step by step create PDF file with digital signature certificate in TCPDF library.
First create Laravel project from the Terminal using bellow command.
composer create-project laravel/laravel tcpdf
We wil use **elibyy/tcpdf-laravel**
package which makes simple and easy to use TCPDF in Laravel. You can also direct Install TCPDF package and use.
First go to the project root directory in Terminal and run the command.
composer require elibyy/tcpdf-laravel
It will install library in the vendor folder.
Open config/app.php file and add provider class in the providers array.
'providers' => [
//...
Elibyy\TCPDF\ServiceProvider::class,
]
Also add facade class in the aliases array.
'aliases' => [
//...
'PDF' => Elibyy\TCPDF\Facades\TCPDF::class
]
Now create route in **routes/web.php**
file. Add this bellow line to create new URL.
<?php
Route::get('/tcpdf', 'HomeController@createPDF')->name('createPDF');
Now create a new controller class with the bellow command.
php artisan make:controller HomeController
And add createPDF method in the **HomeController.php**
. Don’t forget to **use PDF**
class in the top of the class declaration.
<?php
namespace App\Http\Controllers;
use PDF;
use Illuminate\Http\Request;
class HomeController extends Controller
{
/**
* Where to redirect users after login.
*
* @var string
*/
public function createPDF(Request $request)
{
// set certificate file
$certificate = 'file://'.base_path().'/public/tcpdf.crt';
// set additional information in the signature
$info = array(
'Name' => 'TCPDF',
'Location' => 'Office',
'Reason' => 'Testing TCPDF',
'ContactInfo' => 'http://www.tcpdf.org',
);
// set document signature
PDF::setSignature($certificate, $certificate, 'tcpdfdemo', '', 2, $info);
PDF::SetFont('helvetica', '', 12);
PDF::SetTitle('Hello World');
PDF::AddPage();
// print a line of text
$text = view('tcpdf');
// add view content
PDF::writeHTML($text, true, 0, true, 0);
// add image for signature
PDF::Image('tcpdf.png', 180, 60, 15, 15, 'PNG');
// define active area for signature appearance
PDF::setSignatureAppearance(180, 60, 15, 15);
// save pdf file
PDF::Output(public_path('hello_world.pdf'), 'F');
PDF::reset();
dd('pdf created');
}
}
See the available class methods to customize your PDF file. Output() method will save PDF file in the passed location.
Also check certificate location variable is prefix with **'file://',**
otherwise it will return bellow error.
We are also adding content of the blade file. I have added blade file in the view() method. You can also direct add html view content or via view() method. Here is my **resource/views/tcpdf.blade.php**
file sample file.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>TCPDF</title>
</head>
<body>
<p>
This is a <b color="#FF0000">digitally signed document</b> using the default (example) <b>tcpdf.crt</b> certificate.<br />To validate this signature you have to load the <b color="#006600">tcpdf.fdf</b> on the Arobat Reader to add the certificate to <i>List of Trusted Identities</i>.<br /><br />For more information check the source code of this example and the source code documentation for the <i>setSignature()</i> method.<br /><br />
</p>
<a href="http://www.tcpdf.org">www.tcpdf.org</a>
</body>
</html>
That’s it. Now run your Laravel project with php artisan serve command and open your route URL in the browser. A new PDF file is generated in the public folder.
To check if the certificate is installed perfectly, open PDF file in the **Adobe reader**
in Windows operating system and click on the image bellow in the PDF document. It will load certificate.
There are so many features and customizations available in TCPDF. You can check I hope you will like this article.

hi, how could i add two signatures?

Perl script converts PDF files to Gerber format
Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.
The general workflow is as follows:
Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.
#Pdf2Gerb config settings:
#Put this file in same folder/directory as pdf2gerb.pl itself (global settings),
#or copy to another folder/directory with PDFs if you want PCB-specific settings.
#There is only one user of this file, so we don't need a custom package or namespace.
