Simple image glitcher suitable for producing nice looking i3lock backgrounds

#Getting Started

$ git clone https://github.com/r00tman/corrupter
$ cd corrupter && go build
$ ./corrupter -h
$ ./corrupter shots/example.png out.png && xdg-open out.png

Alternatively, you can use go get -u github.com/r00tman/corrupter to install. Then, the binary will be at ~/go/bin/corrupter ($GOPATH/bin/corrupter if $GOPATH is set).

If you're using an Arch-based distro, you can use one of the two AUR packages!

At the moment, you can only pass and output .png images. But that's enough to work well with scrot and i3lock.

#Using with i3lock+scrot / swaylock+grim

As corrupter only glitches the image for a cool background, you'd have to set up a lock script.

Example screenshot lock script:

#!/usr/bin/env bash
scrot "$tmpbg"; corrupter "$tmpbg" "$tmpbg"
i3lock -i "$tmpbg"; rm "$tmpbg"

The script above takes a screenshot with scrot, distorts it with corrupter, and then locks the screen using i3lock.

If you're using i3, you can create the script at ~/.lock, and then add a lock bindsym.

bindsym $mod+Control+l exec --no-startup-id bash ./.lock

#Using pre-corrupted images

Alternatively, you can pre-corrupt an image and always use it (which is faster):

$ ./corrupter shots/example.png ~/.wallpaper.png

and then, in your ~/.config/i3/config:

bindsym $mod+Control+l exec --no-startup-id i3lock -i ./.wallpaper.png

This method is slightly faster since the image processing has been done beforehand.

#Less distorted image

Default config is pretty heavy-handed. To get less disrupted images you may want to reduce blur and distortion:

$ ./corrupter -mag 1 -boffset 2 shots/example.png out.png && xdg-open out.png
