### Some conclusion

Pillow is always faster than ImageMagick. And Pillow-SIMD is faster
than Pillow in 2—2.5 times. In general, Pillow-SIMD with AVX2 almost always
**10-15 times faster** than ImageMagick.
than Pillow in 2—2.5 times. In general, Pillow-SIMD with AVX2 always
**8-20 times faster** than ImageMagick and almost equal to the Skia results,
