What is the difference between Message and Emoji modes?

Message mode optimizes for 480x480 resolution and a ~2MB limit, while Emoji mode optimizes for 128x128 resolution and a strict 64KB limit with reduced color depth.

How does it handle Slack's 64KB emoji limit?

The skill uses aggressive optimization strategies including reducing the color palette (typically 32-48 colors), limiting frame counts, and utilizing specialized saving methods to ensure emojis meet strict Slack upload requirements.

Can I combine multiple animation effects?

Yes, the animation primitives are designed to be composable. You can apply multiple effects, such as combining a bounce motion with a shake effect, to create unique and complex animations.

Does it support text in GIFs?

Yes, it includes typography helpers specifically designed for small GIFs, featuring text-with-outline rendering to maintain readability on dark and light Slack backgrounds.
