Slow performance when adding an image

[JackStromberg]

Describe the bug
Trying to migrate from tcpdf to tc-lib-pdf/tc-lib-pdf-image. When adding images, it takes almost 15-20 seconds more with the same image to add to the PDF between tcpdf and tc-lib-pdf. The goal is to try and set a background to a landscape page.

In tcpdf I have the following:
$pdf->Image('image.png', 0, 0, 279, 216, '', '', '', true, 300, '', false, false);

In tc-lib-pdf/tc-lib-pdf-image I have the following:
$iid01 = $pdf->image->add('image.png');
$iid01_out = $pdf->image->getSetImage($iid01, 0, 0, $page01['width'], $page01['height'], $page01['height']);
$pdf->page->addContent($iid01_out);

If I comment out $iid01_out and adding the image to the page, I still see the long load time of the image ($pdf->image->add).

Is there a different way I should import the image?

Expected behavior
Was hoping for performance to be the same or better than tcpdf.

Logs
Happy to gather additional telemetry, unsure on next steps though.

Environment:

• OS: Debian 12
• PHP version: 8.2
• Version: 8.0.77 / 2.1.2

Thank you!

Hi,
15-20 seconds is way too slow and I haven't yet observed anything like this.
Would you be able to share an image with a minimal code to reproduce this?
