imagejpeg error

[mikeatcityuni]

Hi, we're getting an error with snap when we add a course image in the course settings. Actually we don't even use snap but the error is still reported! We've got version 4.0.5 (2023012400)

debug message:

https://www.php.net/manual/en/function.imagejpeg.php

imagejpeg(GdImage $image, resource|string|null $file = null, int $quality = -1): bool
imagejpeg() creates a JPEG file from the given image.

so it should have 3 arguments but Snap gives it four, when a jpeg is used:

moodle-theme_snap/classes/image.php
line: 189-192

\ob_start();
if (!$imagefnc($newimage, null, $quality, $filters)) {
return false;
}

if png it should be fine as that does take 4 arguments, sure enough, adding a png results in no error
