Add a similar cut out feature for screenshots just like the one in Screenpresto

[AkechiShiro]

Feature Description

I believe this feature would be a very good addition to be on feature par vs this proprietary tool that is available on Windows :

• Link to manual : https://www.screenpresso.com/docs/ScreenpressoHelp.pdf
• Page 55/87

The feature allows to cut an image/crop but either horizontally or vertically of the image and it will automatically restich the rest of the content after the cut out, you can basically cut out content that you do not want to keep in the screenshot.

I have no idea how would one implement such a feature nor do I have read the codebase of flameshot or is familiar with it.

But I believe this feature would be a very good addition to Flameshot.

@mmahmoudian I don't think this is feasible with flameshot because of the way we launch in full screen. If you "cut" a section either vertically or horizontally then the rest of the image would need to stretch (or not be fully screen).

@borgmanJeremy i feel like this is something that can be done by exposing the coordinates of the selected region to a plugin. This operation doesn't sound like a complex operation. I think it can be done for example via the montage subcommand of imagemagic:

https://imagemagick.org/script/montage.php

I assume the same functionality is also available through their library and can be integrated in plugins.

But apart from this issue, and a bit off-topic, since it has come up in other issues as well, maybe we can also have a windowed mode. This can help address other issue such as:

1. Editing pinned images
2. Loading other images from disk and annotate them

@AkechiShiro I agree that this would be an excellent feature. Snagit also has this feature in their editor. I think it is my favorite editing tool.
