Use the GIFBuilder class to add PIL Image frames, then call save with your target color count. Set width and height to 128 for emoji or 480 for message GIFs, and the builder handles palette optimization and looping automatically.

Slack emoji GIFs should be 128x128 pixels with durations under 3 seconds. Use 10-30 FPS and 48-128 colors to keep file sizes small, and enable optimize_for_emoji to automatically resize and reduce colors.

Apply easing functions from the easing module, such as ease_out, bounce_out, or elastic_out, through the interpolate function. This maps linear frame progress to natural acceleration and deceleration curves for motion like bouncing or sliding.

Lower the FPS to 10, reduce colors to 48, shrink dimensions to 128x128, and enable remove_duplicates to drop near-identical frames. The optimize_for_emoji flag combines several of these optimizations automatically.

Yes, load the uploaded image with PIL Image.open and either animate it directly by transforming it across frames or use it as a style reference. The Skill does not include pre-packaged graphics, so all visuals come from uploads or PIL drawing primitives.

Common causes are non-square dimensions for emoji, sizes outside the 64-128 pixel range, or excessive file size from too many frames or colors. Run validate_gif with verbose output to see which constraint fails.
