I wonder if there is there something like a screen magnifier on linux debian?
Or if one can write such a screen magnifier.
Because I don't want to use packages with many dependencies.
I found a solution myself with writing a shell script for this purpose, for all interested, this script only depends on feh and scrot:
#!/bin/sh # Written by Stefan Völkl if ! hash scrot 2>/dev/null && hash feh 2>/dev/null then echo "You need to have scrot and feh installed" exit 1 fi IMAGE="$(mktemp --tmpdir="/tmp" magnified_XXXXX.png)" trap 'rm "$IMAGE"' EXIT scrot "$IMAGE" feh --borderless --image-bg black --fullscreen "$IMAGE"
