How to Add Watermark Image Using Mpdf In Codeigniter?

To add a watermark image using mPDF in CodeIgniter, you first need to create a new mPDF object and then set the watermarks using the SetWatermarkImage() and SetWatermarkText() functions provided by mPDF.

Here is an example of how you can add a watermark image using mPDF in CodeIgniter:

// Load mPDF library
$this->load->library('pdf');

// Create new mPDF object
$pdf = new mPDF();

// Set the watermark image
$pdf->SetWatermarkImage(base_url('path/to/watermark-image.png'));

// Add content to the PDF
$pdf->WriteHTML('<h1>Hello World</h1>');

// Output the PDF
$pdf->Output();

In the example above, we have loaded the mPDF library, created a new mPDF object, set the watermark image using the SetWatermarkImage() function, added some content to the PDF using the WriteHTML() function, and then outputted the PDF using the Output() function.

This will add a watermark image to each page of the PDF generated using mPDF in CodeIgniter.

How to customize the font style of the text watermark in mpdf?

To customize the font style of the text watermark in mPDF, you can use the SetWatermarkText() function along with the SetWatermarkFont() function. Here is an example code snippet:

$mpdf = new \Mpdf\Mpdf();

$mpdf->SetWatermarkText('SAMPLE WATERMARK');
$mpdf->SetWatermarkFont('helvetica', 100); // Set font style and size

$mpdf->WriteHTML('<p>This is a sample text with a watermark</p>');

$mpdf->Output();

In the code above, the SetWatermarkText() function is used to set the text for the watermark, and the SetWatermarkFont() function is used to set the font style (in this case 'helvetica') and font size (100 in this case) for the watermark text. You can adjust the font style and size according to your requirements.

How to add text watermark in mpdf using codeigniter?

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

require_once APPPATH.'third_party/mpdf/vendor/autoload.php';

class PdfController extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }

    public function index()
    {
        $mpdf = new \Mpdf\Mpdf();
        
        // Add text watermark
        $mpdf->SetWatermarkText('CONFIDENTIAL');
        $mpdf->showWatermarkText = true;
        
        // Generate the PDF file
        $mpdf->WriteHTML('<h1>Hello World!</h1>');
        $mpdf->Output('sample.pdf', 'D');
    }
}

1. In the above code, we have set the watermark text to 'CONFIDENTIAL' and enabled the display of the watermark text on the PDF. You can customize the text and styling of the watermark as per your requirements.
2. Finally, you can access the PdfController by visiting the corresponding URL in your browser, and it will generate and download a PDF file with the text watermark.

That's it! You have successfully added a text watermark in mPDF using codeigniter.

How to make the watermark image clickable in mpdf?

To make a watermark image clickable in mPDF, you can use the SetWatermarkImage function to add the image and then use the SetLink function to add a hyperlink to it. Here is an example code snippet to achieve this:

1
2
3
4

require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$mpdf->SetWatermarkImage('watermark.png');
$mpdf->SetLink('http://example.com');
$mpdf->Output();

In this code, we first load the mPDF library and create a new mPDF instance. We then set the watermark image using the SetWatermarkImage function and add a hyperlink to it using the SetLink function with the desired URL. Finally, we output the PDF document.

By adding a hyperlink to the watermark image, users can click on the image to open the specified URL in their browser.

$mpdf->WriteHTML($html);

// Output the PDF
$mpdf->Output('filename.pdf', 'D');

In the above code snippet, we first load the mPDF library in CodeIgniter. Then, we define the path to the watermark image that we want to use. Next, we create a new mPDF object and set the watermark image using the SetDefaultBodyCSS method. Finally, we output the PDF with the watermark image added to it.
