How does this skill optimize GIF file sizes?

It implements strategies such as reducing the color palette to 48-128 colors, lowering the FPS, and removing duplicate frames to meet Slack's strict upload limits.

Can I use my own images with this skill?

Yes, the skill can load user-uploaded images using the Pillow (PIL) library to animate them directly or use them as a reference for colors and style.

What dependencies are required?

The skill requires Python with the pillow, imageio, and numpy libraries installed.

What dimensions are supported for Slack emojis?

This skill defaults to 128x128 pixels for emoji GIFs and 480x480 pixels for message GIFs, ensuring they look great within the Slack interface.

Does it support complex animation effects?

Yes, it includes pre-built logic for easing functions, bounce effects, rotations, fades, and even particle burst explosions.
