flameshot VS kImageAnnotator

For your screenshots simply use Flameshot: https://flameshot.org

First, conceptually this is what I mean: think about when using a good screen-capture/annotation tool like flameshot: you select a region of the screen, and "magic" you can "edit" it, "in situ". No, what I'm talking about wouldn't share any of the same technical underpinnings with the way flameshot works, it would be the live monitor output, not a raster dump of the screen made to look like it's live. And the annotating would be done on a different screen. But as a user, this is pretty similar.

Flameshot is a free and open-source screenshot tool for Linux that allows users to take screenshots of an area, a window or the full screen. It then provides an editor where users can modify the screenshots by drawing on them, adding text, highlighting areas, blurring parts and more. Users can save the screenshots in common image formats like PNG and JPEG, and upload them directly to image hosting sites like Imgur.

I would recommend Flameshot, available on Linux, Windows and Mac.

This https://github.com/flameshot-org/flameshot/issues/1529 mat or may not be an issue for you with Flameshot, but it may be for others. It's solvable if it is an issue by using mandatory access control such as AppArmor or conditional build. Just FYI.

Flameshot viene con todo eso.

Previously Spectacle used the kImageAnnotator library for the annotation function, so when that library got cropping support Spectacle got it too. For better or worse the new UI no longer uses that library, so I'm guessing the Spectacle devs will have to add in cropping support manually now. No clue if there are plans for it unfortunately, but I assume if work gets started on it there will be an update on that bug report.

It's available as a library (https://github.com/ksnip/kImageAnnotator), additionally you can use the --edit-existing flag with Spectacle to edit arbitrary existing images.

Yeah, it's really good. You can thank the author of https://github.com/ksnip/kImageAnnotator/!

That's just the last change that made it to 0.6.0, the actual difference is more like this.

Cropping in Spectacle will only appear when kImageAnnotator 0.6.0 gets released, as noted in the bug report.

I actually just learned about Ksnip, because I first wanted to recommend you KDE Spectacle, but I noticed it didn't show a crop tool. I discovered Spectacle uses Ksnip's kImageAnnotator for editing and thus discovered Ksnip. Somehow Ksnip does show a crop button and other features that are not enabled in Spectacle. I think I like Spectacle more for quickly taking a screenshot, while Ksnip seems nice to have for a quick edit.
