Can I animate my own uploaded images?

Yes, the skill is designed to work with user-uploaded images via PIL, allowing you to split them into frames, apply transformations, or use them as a reference for colors and style.

What are the recommended dimensions for Slack GIFs?

This skill uses 128x128 pixels for custom Slack emojis and 480x480 pixels for standard message GIFs to ensure optimal display quality and performance.

How does this skill optimize file sizes for Slack?

It implements several strategies including lowering the color count (typically to 48 or 128 colors), reducing FPS (10-30), and removing duplicate frames during the save process.

Does it support complex animation effects?

Absolutely. It includes utilities for shaking/vibrating, pulsing, bouncing, rotating, fading, and even creating particle burst or explosion effects.

What Python dependencies are required?

The skill requires the Pillow (PIL), imageio, and numpy libraries to handle image processing and GIF assembly.

デザインツール

Generates and optimizes high-quality animated GIFs tailored for Slack emojis and messages using Python drawing primitives.

The Slack GIF Creator is a specialized toolkit designed to help developers programmatically build animated GIFs that meet Slack's specific technical constraints. It provides a structured workflow for generating frames, applying smooth motion through easing functions, and optimizing output for either small-scale emojis (128x128) or larger message attachments (480x480). By handling complex tasks like color palette reduction and frame validation, this skill ensures that generated animations are polished, professional, and within Slack's file size limits.
