Does this support complex animations like easing or bouncing?

Absolutely. The skill includes built-in easing functions for smooth motion, including bounce, elastic, and ease-in-out effects to make animations look polished.

What are the recommended dimensions for Slack emojis?

For Slack emojis, 128x128 pixels is the recommended standard to ensure clarity and proper display within the chat interface.

Is there a limit to the GIF duration?

While technically flexible, the skill recommends keeping emoji GIFs under 3 seconds to maintain small file sizes and ensure compatibility with Slack's performance best practices.

Can I use my own images with this skill?

Yes, you can upload existing images which the skill can then process, animate, or use as a reference for colors and styles using the Python Imaging Library (PIL).

How does this skill optimize GIF file sizes?

It reduces file size by adjusting frame rates (typically 10-30 FPS), limiting the color palette (48-128 colors), and automatically removing duplicate frames during the save process.
