What are the recommended dimensions for Slack emojis?

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

Can I animate my own uploaded images?

Yes, the skill is designed to work with user-uploaded images using PIL, allowing you to animate them directly or use them as a reference for colors and style.

How does this skill help keep GIF file sizes small?

It implements optimization strategies such as reducing the color palette (48-128 colors), lowering FPS, and automatically removing duplicate frames during the build process.

Does this skill support smooth animation curves?

Yes, it includes a dedicated easing module with functions like ease_in, ease_out, bounce_out, and elastic_out to avoid robotic-looking linear motion.

Why shouldn't I use emoji fonts with this skill?

Emoji fonts are unreliable across different platforms and operating systems; this skill prioritizes drawing graphics from scratch using PIL primitives to ensure visual consistency.
