✨ Adjustable Blur Radius

[JaceThings]

Feature Request Description

Wouldn't it be cool if we could also adjust the amount of blur in the footprint preview? It could just be another slider in the preview menu :)

Warp (https://www.warp.dev/) does this, just as an example.

Just for fun ;p

Final Checks

• My issue title is descriptive
• This is a single feature request (multiple feature requests should be reported individually)

Really cool! In addition, I think it'd be cool to be able to add background patterns (ex. a grid) on top of the blur as well!

oooo, even better, never seen that added to any app 👀

Custom hex code tint maybe too 😄

Alright, so here's a status update on this:

I looked through iTerm2's source code to set the background blur and it looks like it uses a function called CGSSetWindowBackgroundBlurRadiusFunction, and upon further research, I found that it sets the background blur for a window rather than a view itself. For reference, Loop's preview window is actually a window the size of the screen overlayed on top of everything, with a rectangle view that changes its shape of the rectangle based on the selection window action.
Hopefully that makes at least a bit of sense haha

Anyways, I found that this is the function used to make custom blurs of other apps' backgrounds as well, most likely including Warp.
So I guess that the way to go would probably convert the preview view into an actual window so that I can apply custom blur effects on it too :D

@mrkai77 Any update on this?

[mrkai77]

Not yet... but I am planning on doing this soon! For now, I am more focused on fixing bugs :)

Update: With PR #263, I remade the entire preview window to be an actual "window", so that makes implementing this 10x easier!

Okay, so to do this, it will require a private API. This has been decided to not be added to Loop, with that being said, there may be a toggle in the future to add the ability to turn off the blur entirely, which does not require a lot of logic. If i am wrong, and this can be done efficiently, without a private API please feel free to create a PR!
