Pillow-SIMD is a fork of Pillow (Python Imaging Library) that adds SIMD (Single Instruction Multiple Data) optimizations for faster image processing on supporting CPUs. Current version is 9.5.0.post2, built on Pillow 9.5.0. It requires Python >=3.7 and is maintained as a drop-in replacement for Pillow with performance improvements for common operations like resizing, filtering, and color space conversion.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Image

✓ from PIL import Image

✗ import pillow; from pillow import Image

The module is always 'PIL', regardless of which fork is installed.

ImageFilter

✓ from PIL import ImageFilter

Basic image resize using pillow-simd. The API is identical to Pillow; SIMD optimizations are applied automatically.

from PIL import Image # Open an image img = Image.open('example.jpg') # Resize using the optimized LANCZOS filter resized = img.resize((300, 300), Image.LANCZOS) # Save resized.save('output.jpg') # For SIMD-accelerated operations, the same API works. # Ensure you're using pillow-simd, not standard Pillow. print('Pillow-SIMD version:', Image.__version__)

Debug

Known issues

gotchaIf standard Pillow is installed, installing pillow-simd will overwrite it. Both cannot coexist. Check that your environment uses pillow-simd by checking Image.__version__.

fix

Use 'pip install pillow-simd --force-reinstall' to ensure pillow-simd is installed. Verify with 'python -c "from PIL import Image; print(Image.__version__)"'.

affects: all

gotchaPillow-SIMD is built with specific CPU instruction sets (SSE, AVX2). If your CPU does not support them, the library will fall back to standard Pillow code. Performance gains may not be realized.

fix

Check CPU support using 'cpuid' or run a benchmark. If no SIMD support, consider using standard Pillow instead.

affects: all

breakingPillow-SIMD 9.5.0 is based on Pillow 9.5.0 and inherits all breaking changes from that version. Notably, some deprecated constants were removed (e.g., 'NEAREST' replaced by 'Resampling.NEAREST').

fix

Use 'from PIL import Image' and reference resampling filters via 'Image.Resampling.<FILTER>' instead of bare constants.

affects: >=9.0.0
