Distortioner

Telegram bot for distorting pictures, stickers, voice messages and GIFs using Content Aware Scale. Currently resides here: @distortionerbot

Usage

1. You'll need to install ffmpeg and ImageMagick with liquid-rescale enabled. For that you'll need to install liblqr and glib-2.0, then compile from source (using AppImage might work too)
2. Create a bot with @BotFather, then set up a DISTORTIONER_BOT_TOKEN environment variable.
3. Set up DISTORTIONER_ADMIN_ID variable (needed to use /daily, /weekly, /monthly commands to monitor bot usage and to use video stickers distortions)
4. After that grab distortioner from releases or compile using go build command.

Docker support

Fill out your bot token in distortioner.env (and your admin ID if you wish to monitor stats), then launch as usual:

sudo docker run -d --restart unless-stopped \
   --name distortioner \
   --env-file distortioner.env \
   -v /path/to/database/directory:/app/data
   ghcr.io/graynk/distortioner:latest

With Podman:

podman run -d \
   --label "io.containers.autoupdate=image" \
   --name distortioner \
   --env-file distortioner.env \
   -v /path/to/database/directory:/app/data
   ghcr.io/graynk/distortioner:latest
cd ~/.config/systemd/user/
podman generate systemd --new --files --name distortioner
systemctl enable --user container-distortioner.service
loginctl enable-linger $USER

What gets collected

The bot technically is able to see all messages in the group due to limitations imposed by Telegram (I've tried making it work with privacy mode enabled, but this renders /distort command useless).

However, none of it is stored or analysed in any way. The only thing I collect is chat IDs for the stats (so if you use the bot in chat group - I store only chat group ID).

In addition to that, if the bot fails to distort some piece of media, it will not get deleted as well, to help me debug such cases (your user ID is not tied to the file itself)

TODO

• Distort animated stickers
• Make distortion increase throughout the video
• For stickers create and maintain a separate sticker pack for ease of use
• Localization, refactoring, tests
