Generating GIF Animations and Performing Image Manipulation with Python Pillow

To create GIF animations with Python, first install the Pillow library using pip install pillow .

Then use the following script to create a new GIF, open image frames, paste them, set frame duration, and save the animation:

from PIL import Image
# Create a new GIF object
gif = Image.new('RGB', (200, 200), color='white')
# Open frames
image1 = Image.open('image1.png')
image2 = Image.open('image2.png')
image3 = Image.open('image3.png')
# Paste frames
gif.paste(image1, (0, 0))
gif.paste(image2, (50, 50))
gif.paste(image3, (100, 100))
# Set frame delay (milliseconds)
gif.info['duration'] = 500
# Save GIF
gif.save('animation.gif', save_all=True, append_images=[image2, image3], loop=0)

The script demonstrates how to control the delay between frames and generate a looping GIF file.

Additional examples illustrate common Pillow image‑processing operations:

Resize an image:

from PIL import Image
image = Image.open('input.jpg')
new_size = (800, 600)
resized_image = image.resize(new_size)
resized_image.save('output.jpg')

Crop an image:

from PIL import Image
image = Image.open('input.jpg')
box = (100, 100, 400, 400)  # (left, upper, right, lower)
cropped_image = image.crop(box)
cropped_image.save('output.jpg')

Add a text watermark:

from PIL import Image, ImageDraw, ImageFont
image = Image.open('input.jpg')
draw = ImageDraw.Draw(image)
text = 'Watermark'
font = ImageFont.truetype('arial.ttf', size=50)
draw.text((10, 10), text, font=font)
image.save('output.jpg')

Rotate an image:

from PIL import Image
image = Image.open('input.jpg')
angle = 45  # degrees counter‑clockwise
rotated_image = image.rotate(angle)
rotated_image.save('output.jpg')

Apply a blur filter:

from PIL import Image, ImageFilter
image = Image.open('input.jpg')
filtered_image = image.filter(ImageFilter.BLUR)
filtered_image.save('output.jpg')

These examples cover typical Pillow tasks; replace the placeholder file paths with your own images and ensure required fonts are installed for watermarking.
