Does it support smooth animation motion?

Absolutely. The skill includes an easing module with functions for bounce, elastic, ease-in/out, and back-out motion to avoid jerky, linear animations.

Can I use my own images with this skill?

Yes, you can upload existing images and use the provided PIL-based utilities to animate, resize, or transform them into optimized GIFs.

How does this skill optimize GIF file sizes for Slack?

It implements color quantization (reducing palettes to 48-128 colors), manages FPS, and uses a 'remove_duplicates' function to keep files under Slack's upload limits.

What technical dependencies does this skill require?

To run the generated scripts, you will need the Pillow, imageio, and numpy Python libraries installed in your environment.

What are the recommended dimensions for Slack emojis?

The skill recommends 128x128 pixels for emojis and 480x480 pixels for message GIFs to ensure they look crisp across all devices.
