Does this skill handle Slack's specific file size limits?

Yes, it includes specialized optimization strategies like color palette reduction and duplicate frame removal to ensure GIFs meet Slack's strict file size requirements.

Can I use existing images to create animations?

Absolutely. The skill provides utilities to load user-uploaded images via PIL, allowing you to animate existing assets or use them as references for new designs.

What are the recommended dimensions for Slack emojis?

For optimal performance and appearance within Slack, the skill recommends 128x128 pixels for emojis and 480x480 pixels for inline message GIFs.

What easing functions are available for animation?

The skill includes a variety of interpolation methods such as linear, ease_in, ease_out, bounce_out, elastic_out, and back_out for smooth, natural motion.

What dependencies are required to use this skill?

You will need the Pillow (PIL), imageio, and numpy libraries installed in your Python environment to generate and optimize the GIF files.
