Does it support smooth motion and easing?

Absolutely. The skill includes an easing module with functions like bounce_out, elastic_out, and ease_in_out to move objects more naturally than simple linear motion.

What are the recommended dimensions for Slack GIFs?

This skill recommends 128x128 pixels for emoji GIFs and 480x480 pixels for standard message GIFs to ensure they look sharp and load quickly in the Slack interface.

How does this skill optimize GIF file sizes?

It employs several strategies including reducing the color palette (typically to 48-128 colors), lowering the frame rate, and utilizing a 'remove duplicates' feature during the saving process.

Can I animate my own uploaded images?

Yes, the skill can load existing images using the Pillow (PIL) library, allowing Claude to manipulate, crop, or apply animation effects to your specific assets.

What Python libraries are required?

To use the Slack GIF Creator utilities, you need to have Pillow, imageio, and numpy installed in your environment.
