slack-gif-creator

Toolkit for creating optimized animated GIFs for Slack with strict size and quality constraints.

• Utilities to build and validate animated GIFs for Slack
• Supports emoji and message-sized GIFs with specific dimensions
• Includes easing, frame composition, and drawing primitives
• Enables creation of polished, visually engaging animations

• Dimensions: emoji 128x128, message 480x480
• FPS 10-30, colors 48-128, duration under 3s for emoji
• GIFBuilder assembles frames and optimizes for Slack
• Validators check if GIF meets Slack requirements
• Easing functions for smooth motion (ease_in, ease_out, bounce_out)
• Frame helpers for common graphics (blank, gradient, star, text)
• Use PIL primitives for drawing (circles, lines, polygons)
• Avoid emoji fonts or pre-packaged graphics

1. 1.Create GIFBuilder with desired dimensions and FPS
2. 2.Add frames using add_frame() or add_frames()
3. 3.Apply easing or animation concepts (pulse, bounce, fade, etc.)
4. 4.Save with optimize_for_emoji=True and appropriate color count
5. 5.Validate output with is_slack_ready() or validate_gif()
6. 6.Use frame helpers for common shapes and effects
