Spectacle issue

[chimak111]

I came across How to remove empty space when window capture with Spectacle but can't respond there because I've forgotten how to log in there. (I could at one time!)

Perhaps, the OP could try disabling compositing just before taking the active window's screenshot. That'll get rid of the empty space (and reduce the file size a bit) by excluding the "shadow" effect.

Of course this won't work on Wayland.

Disabling compositing had no effect for me. So, how do you get rid of that border, when using Spectacle to capture the window under the cursor?



viewing on KFN doesn't show the border, but right-click, open image in new tab, and there it is. One might not see it if you don't use a light theme, but I see it in chromium with the classic theme.

I've found that capturing the "Active Window" doesn't do it. I wonder how the Neon folks get on with their newer versions.

On X11, I disable/enable compositing with Shift+Alt+F12 and I can verify the state by running

qdbus org.kde.KWin /KWin supportInformation | grep -i composi

$ qdbus org.kde.KWin /KWin supportInformation | grep -i composi
Composite: yes; Version: 0x4
compositingMode: 1
useCompositing: true
windowsBlockCompositing: true
Compositing
Compositing is active
Compositing Type: OpenGL
$ qdbus org.kde.KWin /KWin supportInformation | grep -i composi
Composite: yes; Version: 0x4
compositingMode: 1
useCompositing: true
windowsBlockCompositing: true
Compositing
Compositing is not active
$

The first output has compositing active. The second doesn't.

For me, disabling compositing using the Alt+Shift+F12 toggle is enough. I do that, take the screenshot of the window under the cursor, and then restore compositing.

Here are two images taken in KDE neon (Plasma 5.22.5; X11). Turning off any dark style sheet for KFN is required.

Compositing on:



Compositing off:



In Gwenview one can set the bg to white to see the border aka shadow clearly. The metadata shows the image taken with compositing to be larger (1150x859) because of the shadow effect than the image taken without compositing (1020x729). The size of the object itself in both cases is the same. One could check that with something like kruler.

====================

For both X11 and Wayland, there's another route to alter the shadow's dimensions: System Settings > Appearance > Application Style > Window Decorations > Theme > click on the pencil icon and choose the desired shadow dimensions (from none to very large).

Thanks! But I found my username/password. So all set.

Yes, that's the one
