effect-scale doesn't seem to do anything

[luispabon]

As per title. effect-scale=2 or 200 or whatever seems to have no effect, at least from config file:

font=Ubuntu

timestr=%R
datestr=%a, %e of %B

effect-scale does scale the image; if your screen is 1920x1080, effect-scale=2 should mean the background image is 3840x2160. However, the default scaling mode is fill, so that 3840x2160 image is being scaled back down to fill the screen when it gets rendered.

You can try to add scaling=center; that should make swaylock just show the center of the scaled image.

The main reason I added scaling is that --effect-scale=0.5 --effect-blur=7x5 --effect-scale=2 is way faster than blurring the entire screen, and that the lower quality isn't noticeable at 4k. A secondary reason was that --effect-scale=0.1 --effect-scale=10 has a sort of neat pixelation effect. I didn't consider that someone would want to actually zoom in, but that's obvious in retrospect. I'll add something about that to the documentation.

Copy that, looks like I misunderstood how the feature works :+1:

I'm curious, what did you think the feature did? Does --effect-scale=2 --scaling=center do what you were trying to do, or were you trying to do something else?

I'm asking because if you were trying to do something else, there might be a cool new feature idea there which I could try to implement.

Well, I hadn't seen --scaling on the docs so I assumed when scalingx2 the lock screen would show the image scaled 2x2 while centered. The reason I wanted to blow the image bigger was to avoid being too obvious about what was on either of my screens without resorting to massive blurring.

Side note: kudos for seamless multimonitor support btw.
