I would like to scroll through a series of images and take and save the same screenshot of a fixed area over and over again.
It’s not a problem to define a rectangular area for a screenshot and save this in a numbered file, but ATM I have no idea how to make it work to make further screenshots from the same area without the spectacle dialogue.
Do you know a way to solve this?
Hi Gagl
Do you care about image quality?
Taking a shot of the Desktop showing an image viewer compared to a portion of an image from an image editor can be very different.

You could record your session with OBS, you can record a limited area on the screen - then playback with MPV fullscreen, and press ‘screenshot’ every time you want a frame extracted.
Also try spectacle:
Launch Krunner.
Type spectacle -br and hit Enter two times.
spectacle -b, --background
So in krunner, I did ‘spectacle -br’ and hit ‘enter’.
Next time, I pulled up krunner and hit ‘enter’ to launch the same command, then ‘enter’ to execute/save the image.
@ben2talk:
With this method spectacle asks for any screenshot for the coordinates.
I have more than 500 x-ray images in a special format, which I can view with a dedicated program. I can scroll through them with PgUp/PgDn.
And now I need a screenshot tool, that i can use with only one other key (PrintScreen or any else).
Spectacle offers the option of taking screenshots with the config of former shots. But this option is only usable via option menu and doesn’t react on a key.
At least I haven’t found a way to do this yet. Perhaps I have simply overlooked something.
@vektor:
I need the original screen resolution.
Dunno what version of plasma you’re using but… Here’s an example using Ksnip. That screenshot tool does have a -l command. Screenshot of the last rectangular area. In this case I made a simple bash script for it and, for the sake of it, added it to the Ksnip desktop application ( you could assign a shortcut for it of course). Again, dunno what plasma you’re on and which screenshot tool is available at the moment with such a command. But if I understand the topic correctly, this is a way to do it. Mind you, there already is such a command in the ksnip desktop app. It’s just to show a maybe how-to.
Flameshot too has an option to take a screenshot of the last selected area. You only need to assign a shortcut to flameshot application if the option is ticked. I’m not really sure but I believe Flameshot is available for plasma 6 if that should be the case.
Hi Gagl
Confused by terminology.
“I need the original screen resolution” and yet a screenshot program is being discussed. Do you mean the original image resolution?
A screenshot program will not care about the resolution of the original image and will only grab from the current display. If that is all you need then dzon has you covered.
Can you please clarify?

i tried the krunner line and it captured the same part of the screen as i last used from the prt sc button way.
it seems to remember or use that config, so open the settings and change it to look like this, then try the krunner command.
You’re right. Unless I’m missing the point of the question, this is a good way to do it. However, I can’t seem to find a way to hide the spectacle window once the shot’s been taken.
I mean, I can set ksnip so that I can simply click non stop, set to a certain rectangular area and autosaved, no ksnip window involved.
If spectacle is set to the above config, the second shot will take a shot of spectacle if it isn’t closed first. Not reeeally a biggie, just a timesaver. Dunno if that function is implemented in spectacle really. I guess you’d have to start spectacle in -b and use the other settings in the gui config.
Screenshot is just click click click…
yes, once the GUI is set up to use and remember the area you need, then just use the krunner (or make a shortcut key for it) and you won’t have to see the GUI interface each time.
of course it also help to have spectacle set to save to your default folder so it doesn’t have to ask you where to put it.
Myeah…It still misses out. You need to create a desktop app if you want to achieve what ksnip does. First you need to set the settings in spectacle and then you either adjust spectacle to launch with -b -r or you make a separate app for it.
Edit: Can’t get it to work. Maybe I’m missing out on something but even with the settings done in the gui, it’ll pop up the selection marker. There isn’t a last rectangular command in the command line. Maybe in the latest version, not in this one.
Hi all,
many thanks for the extensive help and the many tips.
All of the screenshot tools you mentioned had the disadvantage that it was not possible to save a screenshot simply by pressing a button without further interaction.
Perhaps I didn’t find all the parameters/possibilities of the tools, but at some point I didn’t feel like it anymore… (I need this for work and can’t waste hours on it)
I’ve uninstalled all the garbage and now create lots of numbered full screenshots with the KDE standard Spectacle.
Further processing is then performed with ImageMagick tools (convert --crop), then baked together to a PDF (convert filelist blah.pdf), what is then shrinked via ghostscript (~150MB → 20MB).
I have integrated all this into a script (what a nice exercise for bash scripting).
Now is all done, my colleagues can view the numerous processed screenies in one file.
I posted exactly that option. Click click click was the only thing needed. But hey, whatever works for you.
