Can I animate my own uploaded images?

Absolutely. The skill provides utilities to load existing images via PIL, allowing you to animate them, split them into frames, or use them as reference for new designs.

What kind of animation effects can I create?

The skill supports various complex animations including shaking, pulsing, bouncing, rotating, fading, and even particle bursts using professional easing functions.

Does this skill help with Slack's file size limits?

Yes, it includes specific optimization strategies such as reducing the color palette to 48-128 colors and lowering FPS to ensure GIFs remain under Slack's upload thresholds.

What dimensions are used for Slack GIFs?

It uses Slack-recommended dimensions: 128x128 for emojis and 480x480 for standard message GIFs, ensuring your content looks sharp on all devices.

What Python libraries are required to run the generated code?

The core dependencies for the generated animation scripts are Pillow, imageio, and numpy.
