How to add a watermark with Yii2 kartik-mpdf - php

Question

How can I add watermark image on pdf using kartik-pdf?
Here is the line I added:
'options' => [
'title' => 'Title',
'showWatermarkText' => true,
'showWatermarkImage' => true,
],
// call mPDF methods on the fly
'methods' => [
'SetHeader' => ['Title'],
'SetFooter' => ['{PAGENO}'],
'SetWatermarkText' => ['DRAFT'],
'SetWatermarkImage' => $basepath . '/images/imgbox1.jpg',
]
Only the text watermark display.
Is there something wrong on how I used watermarkImage?

Answer 1

use kartik mpdf library to create object of mpdf;
The following code will create simple pdf using kartik widget
use mPDF;
class SiteController extends Controller
{
public funtion createpdf()
{
$HTML='your html content';
$mpdf = new \Mpdf\Mpdf(); //please use your kartik mpdf object here
$mpdf->SetWatermarkImage('../images/background.jpg');
$mpdf->showWatermarkImage = true;
$mpdf->WriteHTML($HTML);
// Saves file on the server as 'filename.pdf'
$mpdf->Output('filename.pdf', \Mpdf\Output\Destination::FILE);
}
}

Answer 2

Set the SetWatermarkImage property as an array, like this:
// call mPDF methods on the fly
'methods' => [
'SetHeader' => ['Title'],
'SetFooter' => ['{PAGENO}'],
'SetWatermarkText' => ['DRAFT'],
'SetWatermarkImage' => ['/images/imgbox1.jpg'],
]
Also, you have to check the image path. You used the $basepath, I usually don't use it, since my images folder is already inside my web folder.
