Args: frames: List of PIL Image objects output_path: Output file path duration: Duration per frame in milliseconds """ frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=duration, loop=0, # 0 = infinite loop optimize=True ) ``` ### Simple Animation Example ```python from PIL import Image, ImageDraw def create_bouncing_ball_gif(output_path): frames = [] size = 128 ball_radius = 20 # Create 20 frames for i in range(20): img = Image.new('RGBA', (size, size), (255, 255, 255, 0)) draw = ImageDraw.Draw(img) # Calculate ball position (bouncing) y = int(abs(math.sin(i * 0.3) * 50) + 30) # Draw ball draw.ellipse( [size//2 - ball_radius, y - ball_radius, size//2 + ball_radius, y + ball_radius], fill='#FF6B6B' ) frames.append(img) # Save as GIF frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=50, loop=0, transparency=0, disposal=2 ) ``` ### Text Animation ```python from PIL import Image, ImageDraw, ImageFont def create_typing_gif(text, output_path): frames = [] size = (200, 50) try: font = ImageFont.truetype("/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf", 24) except: font = ImageFont.load_default() # Create frame for each character for i in range(len(text) + 1): img = Image.new('RGB', size, 'white') draw = ImageDraw.Draw(img) draw.text((10, 10), text[:i] + "_", fill='black', font=font) frames.append(img) # Add cursor blink at end for _ in range(3): img = Image.new('RGB', size, 'white') draw = ImageDraw.Draw(img) draw.text((10, 10), text, fill='black', font=font) frames.append(img) img = Image.new('RGB', size, 'white') draw = ImageDraw.Draw(img) draw.text((10, 10), text + "_", fill='black', font=font) frames.append(img) frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=100, loop=0 ) ``` ## Optimization Techniques ### Reduce File Size ```python from PIL import Image def optimize_gif(input_path, output_path, max_colors=64): """Optimize GIF for smaller file size.""" img = Image.open(input_path) # Reduce colors frames = [] try: while True: frame = img.copy() frame = frame.convert('P', palette=Image.ADAPTIVE, colors=max_colors) frames.append(frame) img.seek(img.tell() + 1) except EOFError: pass frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=img.info.get('duration', 100), loop=0, optimize=True ) ``` ### Reduce Dimensions ```python def resize_gif(input_path, output_path, max_size=128): """Resize GIF to fit within max dimensions.""" img = Image.open(input_path) # Calculate new size maintaining aspect ratio ratio = min(max_size / img.width, max_size / img.height) new_size = (int(img.width * ratio), int(img.height * ratio)) frames = [] try: while True: frame = img.copy() frame = frame.resize(new_size, Image.LANCZOS) frames.append(frame) img.seek(img.tell() + 1) except EOFError: pass frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=img.info.get('duration', 100), loop=0, optimize=True ) ``` ### Reduce Frame Count ```python def reduce_frames(input_path, output_path, keep_every=2): """Keep only every Nth frame.""" img = Image.open(input_path) frames = [] frame_num = 0 try: while True: if frame_num % keep_every == 0: frames.append(img.copy()) img.seek(img.tell() + 1) frame_num += 1 except EOFError: pass if frames: frames[0].save( output_path, save_all=True, append_images=frames[1:], duration=img.info.get('duration', 100) * keep_every, loop=0 ) ``` ## Animation Ideas ### Emoji Reactions - Thumbs up appearing - Heart beating/pulsing - Star spinning - Checkmark drawing itself - Fire flickering ### Status Indicators - Loading spinner - Progress dots - Typing indicator (...) - Pulse animation ### Celebrations - Confetti falling - Sparkles twinkling - Party popper exploding - Balloons floating ## Validation Script ```python from PIL import Image import os def validate_slack_gif(path): """Check if GIF meets Slack requirements.""" issues = [] # Check file size file_size = os.path.getsize(path) if file_size > 128 * 1024: issues.append(f"File size {file_size/1024:.1f}KB exceeds 128KB limit") # Check dimensions img = Image.open(path) if img.width > 128 or img.height > 128: issues.append(f"Dimensions {img.width}x{img.height} exceed 128x128") # Check format if img.format != 'GIF': issues.append(f"Format is {img.format}, not GIF") if issues: print("❌ Issues found:") for issue in issues: print(f" - {issue}") return False else: print("✅ GIF meets Slack emoji requirements!") return True ``` --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/chenycl) — claim your Tome and manage your conversions.
