Is there a way to turn a `Makie.contour` plot into an array? Either where the contour pixels are 1s and everything else is 0 or where the pixels enclosed by the values are 1s and everything else is a 0. I can use `ImageEdgeDetection.detect_edges` to get a contour array but it’s much different than what `Makie.contour` returns

`Makie.colorbuffer(ax.scene)` would give you pixels. A contour plot uses lines, so the underlying information is not represented as pixels. We use Contours.jl, so you could also call that directly if you need that data.
