cairometal
A pycairo-compatible 2D vector-graphics backend that renders on the Apple GPU via Metal.
Independent project — not affiliated with the cairo graphics library or the official
pycairobinding. It reimplements a compatible surface/context API on top of Metal.
Requirements
- macOS (Apple Silicon). Metal is an Apple framework; there are no Linux/Windows builds.
- Python 3.10+.
Install
pip install cairometal
Wheels are published per-CPython-version for macOS arm64. There is no on-the-fly compilation at install time — you get a prebuilt binary.
Usage
The API mirrors pycairo, so existing pycairo code largely works by changing the import:
import cairometal as cairo
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 256, 256)
ctx = cairo.Context(surface)
ctx.set_source_rgb(0.13, 0.42, 0.96)
ctx.rectangle(32, 32, 192, 192)
ctx.fill()
ctx.set_source_rgb(1, 1, 1)
ctx.move_to(60, 140)
ctx.set_font_size(40)
ctx.show_text("Metal")
surface.write_to_png("out.png") # rasterized on the GPU
What it is
cairometal implements cairo's drawing model — paths, fills, strokes, clips,
groups, gradients, text, image surfaces, PNG output — with the rasterization
running on the GPU through Metal. It's useful where you have GPU-bound 2D vector
work; for light/typical cairo workloads the CPU pycairo is perfectly fine.
