Can I use this skill to create standard message GIFs?

Yes, the toolkit supports message GIFs with a 2MB limit and optimal dimensions of 480x480, providing higher frame rates and color counts than emoji mode.

What is the file size limit for Slack emojis?

Slack has a strict 64KB limit for custom emoji GIFs. This skill includes built-in validators and optimization strategies to help your creations stay under this limit.

How do I ensure my GIF is ready for upload?

The skill includes a 'is_slack_ready' function that runs comprehensive checks on dimensions and file size to confirm compatibility before you attempt to upload to Slack.

What animation effects are included?

The library features a wide range of primitives including shake, bounce, spin, pulse, fade, zoom, explode, wiggle, slide, flip, morph, and kaleidoscope effects.

Does it handle text rendering for small sizes?

Yes, it includes helper utilities for rendering text with outlines, which significantly improves readability at the small scales required for Slack emojis.
