PowerBlur is an image blurring tool based on Pillow, offering a high degree of freedom. It can achieve effects similar to the frosted glass effect found in systems like Windows/Mac (?).
pip install PowerBlurfrom PIL import Image
import PowerBlur
# Load the image
image = Image.open("image.jpg")
# Get image size
width, height = image.size
# Create a blur processing object
blur = PowerBlur.PowerBlur(image, (int(width*0.1), int(height*0.1), int(width*0.9), int(height*0.9)))
# Apply the blur effect
blurred_image = blur.draw()
# Save the blurred image
blurred_image.save("output.jpg")| Parameter | Required/Default Value | Type | Description |
|---|---|---|---|
| image | ✔️ | Image | The image to be processed |
| size | ✔️ | tuple/list | The area of the image to be processed, in the format (x1, y1, x2, y2) |
| radius | ❌ (default is 25) | int | Corner radius; 0 means no corner radius |
| mask_fill | ❌ (default is (255, 255, 255)) | tuple/list | Mask color (R, G, B) |
| mask_alpha | ❌ (default is 100) | int | Mask opacity (0~255); 0 is fully opaque, 100 is fully transparent |

| noise_std | ❌ (default is 10) | float | Gaussian noise standard deviation; 0 means no noise |
| sigma | ❌ (default is 5) | float | Gaussian blur parameter; 0 means no blur |
| exposure | ❌ (default is 1) | float | Exposure (0~10); 0 means no exposure |
| saturation | ❌ (default is 1) | float | Saturation; 0 means no saturation |
