Create a minute-long countdown gif.
Make sure you have the Pillow library installed:
pip3 install Pillow
Put a TrueType font in the repository root directory as font.ttf.
Run the script with the countdown target time as a parameter:
python3 gif.py "2019-03-30T15:00"
The time format is %Y-%m-%dT%H:%M, or YYYY-MM-DDTHH:MM. The script works in all UTC.
Copy default_config.py to config.py to override the default configuration.
Copy default_end.png to end.png to override the default image used for drawing the ends of the background. The height of the image should match your IMAGE_HEIGHT variable. Only the alpha channel is used – it will be colored in according to your BACKGROUND_COLOR variable.
