name: slack-gif-creator description: Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like "make me a GIF of X doing Y for Slack."

Slack GIF Creator

Overview

Toolkit for creating Slack-optimized animated GIFs with technical specifications, Python utilities, and animation concepts.

Key Dimensions & Parameters

Size Requirements:

• Emoji GIFs: 128x128 pixels
• Message GIFs: 480x480 pixels

Performance:

• FPS range: 10-30 (lower = smaller files)
• Color palette: 48-128 colors
• Duration: Under 3 seconds for emoji

Core Utilities

Copyfrom gif_builder import GIFBuilder
from validators import validate_gif
from easing import ease_in_out

# Create a simple animated GIF
builder = GIFBuilder(size=(128, 128), fps=15)
builder.add_frames(frames)
builder.save("output.gif")

# Validate for Slack
validate_gif("output.gif", target="emoji")

Animation Techniques

• Shake/Vibrate: Oscillating position offsets
• Pulse/Heartbeat: Rhythmic scaling
• Bounce: Gravity with easing functions
• Spin/Rotate: Angular transformations
• Fade In/Out: Alpha channel adjustments
• Slide: Directional movement with easing
• Zoom: Scale and crop operations
• Explode/Particles: Radiating burst effects

Design Philosophy

Create polished graphics using PIL primitives:

• Use thicker lines (width >= 2)
• Layer shapes for depth
• Vibrant colors with contrast
• Calculated symmetry for complex forms

Dependencies

Copypip install Pillow imageio numpy

Quick Start

Copyfrom PIL import Image, ImageDraw
import imageio

frames = []
for i in range(20):
    img = Image.new('RGBA', (128, 128), (0, 0, 0, 0))
    draw = ImageDraw.Draw(img)
    # Animation logic here
    frames.append(img)

imageio.mimsave('output.gif', frames, fps=15)
