Lovely

Lovely is a python library that inserts emojis to images with a face, an unexpected way to improve team morale and engagement. Example of usage in slack:

This library uses face detection via OpenCV, so emojis don't cover face.

How to add emoji to Slack?

Here is the Slack tutorial

Requirements

1. Python 3
2. Run pip install -r requirements.txt (opencv, numpy, optional slack sdk). If you don't want to install/use slack sdk, you can remove it from requirements.txt.

How to run script

Default usage: script will output an image with -lovely suffix and ❤️ emojis: python main.py path/to/image.jpeg

[WIP] To customize emojis pass style parameter: [lovely, rage, sad] or all(will generate images for all styles). Example: python main.py path/to/image.jpeg rage

Why insert emoji image and not just ❤️?

I tried to use Pillow to write emojis directly, but it doesn't work as expected. If you want to fix it, just do it.

Slack part

To add an emoji to a slack workspace one needs admin.emoji.add access which is part of admin.teams:write scope. It's highly unlikely that anyone will install a Slack app with such scope for just emoji, so the implementation looks like this:

1. Anyone installs the app to a workspace
2. A user who wants to add a emojis to a workspace sends a message to the app with a photo(s).
3. The app responds with a message to the user with lovely emojis on the input photo(s(), which they can use later when adding an emoji.

How to run slack part

To run slack part, export env params with your app values: SLACK_SIGNING_SECRET and SLACK_BOT_TOKEN and run python slack.py.
