Ich wusste bis eben nicht, daß man Maimais auch durchspielen kann.

Well if you want modern CSS3-support or even JS you have to go for a browser. You could try NetSurf which is a very small & fast but only supports CSS2. Or Dillo, which is even smaller & faster (but also more limited in terms of CSS support)

The very basic version only allowing for one filter would be EasyEffects. If you want to use different filters for different programs you can install some LV2-plugins or bundles and then configure LV2-Plugins directly in pipewire (which is a bit of a pain) or use a GUI plugin-host like Calf and probably some patchbay (qpwgraph, patchmatrix, ...)

Or even better: try Carla, it may be a exactly what you want and can be remote controlled via MIDI or OSC

Ha! Na das nenne ich mal ne produktive Mittagspause ;p

from PIL import Image
from numpy import array, vectorize
i = array(Image.open("stego.png"))
n = vectorize(lambda p: (p & 0x01) * 255)(i)
Image.fromarray(n).save("antistego-py.png")

library(png)
i <- readPNG("stego.png")
for (p in 1:3) i[,,p] <- (i[,,p] * 255) %% 2
writePNG(i, "antistego-r.png")

magick stego.png -fx "(p * 255) % 2" antistego-magick.png
