Id doesnt work

Could you do the working example? It wants some $file. If i put there any image or txt I've got an empty page.
$file = 'myimage.png';
pdf->buildImage()->setFile($file)

I think you have missed render() call.

$file = 'myimage.png';
pdf->buildImage()
->setFile($file)
->render();

Alternatives are write/put (aliases).

PS: I was experimenting with calling render() in __destructor
so that it would not be necessarily to invoke every time, but
unfortunately the object is somehow released when executing
destructor (you can't call any methods on the object).

Thank you for your answer. TCPDF is new for me. I just want to see what it can do. And therefore I may make shameful mistakes.

Unfortunately I have again white page. No errors, nothing.
Here is whole code of my example.php

include 'tcpdf/vendor/autoload.php';
include 'vendor/autoload.php';
error_reporting(E_ALL);
class PDF extends TCPDF {
use \org\majkel\tcpdfwarper\TCPDFWarperTrait;
}
$file = '14143073744500.jpg';
$pdf = new PDF();
$pdf->buildImage()->setFile($file)->render();

I will than post complete working example withing few hours.

Working example: examples/example-01.php
If inaccessible yet, goto: https://github.com/majkel89/tcpdf-warper/blob/master/examples/example-01.php

Thanks a lot. Now it's really clear for me. That's very usefull.

That is very nice to here.

I'm looking forward for any suggestions about further extending this tiny library.

PS: I'd be grateful if you rank me class if you really like it.
