Watermark an image in KDE Plasma desktop

Desktop Environments Plasma
1

In Cinnamon, one can keep an image as a watermark on top of the desktop, with this extension.

enter image description here

This is a screenshot of my desktop (Linux Mint 19) from April 2019. The cat is added as a watermark. Its position and transparency can be changed.

Is there any extension/widget in KDE which enables this feature?

Note: The cat in this image is just a floating widget like the clock or the system monitor applet. I can change the desktop wallpaper without moving the cat, and I can move the cat around without modifying the wallpaper.

Hello.

KDE has a powerful application which can handle many things.

You can use Digikam, it is available in KDE repository.

In terminal enter :

yay -S digikam

And the guide to follow the usage is :

https://userbase.kde.org/Digikam/Watermark

The watermark extension in cinnamon is like another dynamic wallpaper on top of the desktop, whose position can be changed.

I am not looking for how to stitch two images.

Both Cinnamon and GNOME like to provide extensions. KDE do not provide lots of utility extension like these, rather it provides utility software of its own.

I also checked in the KDE store whether there are any widget available or not for carrying out the process, but the nearest thing was to watermark PDFs.

  • If don’t want to use Digikam, then your can use imageMagick.
  • This little utility tool might be installed in you Desktop, as I also have it.
  • Then, you can add watermarks to the image via terminal only !

See the guide :

But I am not sure whether it can add image or not.





And adding image over image can also be accomplished by any paint software like krita, GIMP, Kolourpaint, etc…




If you desperately need an extension, then you can try to add extension to FireFox.

I found a GUI tool for ImageMagick, by which you can change the position of watermarks.

@SearingSunrazeSmash Thank you for your reply, but you probably did not understand what I am trying to do. The cat in this image is just a floating widget like the clock or the system monitor applet. I can change the desktop wallpaper without moving the cat, and I can move the cat around without modifying the wallpaper.

Off topic, but I was just wondering what dock you are using in that screenshot ? Looks really nice.

It was Docky (now discontinued).

I’m sorry but the only thing I’ve found in Kde is a tool that leaves a tab as a watermark (I take a photo because it can’t be seen with Spectacle).

(The image tab is minimized but the watermark stays and overlaps even applications).

I don’t know if there is any way to do what you say.

Oh, what absolute twaddle! KDE has more widgets and “Plasmoids” than any other DE. You can clutter your desktop to your heart’s content on KDE.

In the case of OP, the solution is very simple, no need to install anything. KDE Plasma comes with a widget called Media Frame:

You can resize it and position it however you want. It can have a border (frame) or not. It can be one or more picture or video files, or even a folder full of pictures (which will then be like a slideshow). If you don’t want a border around the picture, make sure the picture format supports transparency (PNG and SVG are good candidates).

Thanks for it. I had never used it, and also I got wrong impression of the question asked in this topic.

This should be the solution then.
:vulcan_salute:

Absolutely :100:!!

Despite using KDE, I wrote wrong information. :rofl: :rofl:

This is what happens when not the forum for the time…


Also this might be due to the fact that GNOME highly relies on extensions, unlike KDE !

For transparent images, the background can be removed by going to Edit Mode and toggling Show/Hide Background.
