How does this skill optimize GIFs for file size?

It utilizes strategies like reducing the color palette (to 48-128 colors), lowering FPS (10-30), and removing duplicate frames to ensure compatibility with Slack's upload limits.

Why should I use this instead of a standard GIF generator?

This skill is specifically tuned for Slack's technical requirements, ensuring your creations aren't rejected for size or dimension issues while giving you programmatic control over every frame.

What are the recommended dimensions for Slack emojis?

For Slack emojis, 128x128 pixels is recommended. For standard message GIFs, 480x480 pixels is the standard size.

Does it support complex animation effects?

Yes, the skill includes specialized modules for easing functions (like bounce, elastic, and ease-out) and provides logic for particle bursts, rotations, and shakes.

Can I use my own images with this skill?

Yes, the skill can load user-uploaded images via the PIL library to use them directly as animation frames or as visual inspiration for new designs.
