Black Background on watermark PNG

[anglotopia]

🎯Description of the issue

I have turned watermarks on. On some images there's a black background to the watermark, on others, there is not. See here: http://britmemes.com/image/94118869-10157011942085846-5640909501382000640-n.tQvS

I do not want a background on the watermarks. A transparent PNG is supposed to be a transparent PNG.

▶🚶‍Reproduction steps

1. It does it no matter what I do.

😢Unexpected result

Watermarked images have a black background when the PNG is transparent.

Can you send the watermark and the conflicting images? I need to try these.

 

[anglotopia]

Sure no problem.
I sent examples where the black background is appearing.

Then the file 'Zooming-royle-family.jpg is one where the black background does not appear.

It is not consistant.

I wasn't able to replicate the issue. Here: https://demo.chevereto.com/image/93013841-1330618347146963-4694849702108069888-n.XBesi

Most likely you need to rebuild PHP with GD, this is what I've in the demo: Version 2.2.5 JPEG:1 GIF:1/1 PNG:1 WBMP:1 XBM:1

Chances are that you are using a outdated version or the opposite, a dev one.

 

[anglotopia]

Hmmm I doubt that is the issue - I have two other instances of Chevereto running on the same server and the watermarking works fine. Must be the images I'm working with. Might just nuke the install and try again, it's not a production site yet anyway. I'll post here if that fixes it.

Cheers,
Jonathan

Hi, it is still giving you issues or it is working for you?

 

[anglotopia]

Yes, it's still doing it even after a re-install. I've found it's doing it on lower resolution images. Higher resolution images it doesn't do it.

Which GD version reads on /dashboard ?

Also, you could use the demo info page. Chances are that your PHP is targeting a faulty GD version or something of that kind.

https://demo.chevereto.com/phpinfo.php

 

[anglotopia]

This is what the dashboard says.

 

[Rodolfo]

The issue could be the outdated GD version that is bundled there, 2.1.0 is very old https://github.com/libgd/libgd/releases

 

[anglotopia]

I have no idea how to update that. Can you point me to directions?

I have root/terminal access on my server.

 

[Rodolfo]

sudo apt install php-gd

 

[anglotopia]

That doesn't work. It just says command not found. It's a CentOS WHM sever.

I'm sorry, I shouldn't have omitted all the usual intro of "you have to make it from source or install it from the package manager for your distribution".

I don't run CentOS WHM but I suppose you have to follow their guides on how to update a package. It must be documented somewhere, just make sure to follow the instructions for your systems versions, maybe is just EasyApache.
