Can I use my own images with this skill?

Absolutely. You can load existing PNG or JPEG images via PIL and use them as frames, backgrounds, or as reference material for new animations.

Does this skill support Slack emoji constraints?

Yes, it includes specific presets for 128x128 dimensions and color palette optimization (down to 48 colors) to ensure GIFs meet Slack's strict upload limits.

Do I need to install external software to use this?

It relies on standard Python libraries like Pillow, imageio, and numpy, which are easily installed via pip and managed within your dev environment.

How do I keep my GIF file size small enough for Slack?

The skill includes an optimization suite that allows you to reduce frame count (FPS), limit color depth, and remove duplicate frames automatically during the saving process.

What kind of animation effects are available?

The toolkit provides logic for shakes, pulses, bounces, rotations, fades, slides, zooms, and particle bursts using professional easing functions.
