Modern Python Image Processing Library Everything Pillow does, and everything it couldn't.

from lilow import LilowImage

# Chainable API
img = LilowImage.open("photo.jpg")
result = img.brightness(1.2).contrast(1.1).sharpen(1.0).vignette(0.3).save("out.jpg")

# HDR tonemapping
LilowImage.open("hdr.exr").tonemap(method="aces").save("out.jpg")

# 3D rendering
from lilow.threed import Scene, Mesh, Light
scene = Scene()
scene.add(Mesh.sphere(radius=1.0))
scene.add(Light.directional(direction=(1, -1, -1), color="white"))
scene.render(800, 600).save("sphere.png")
