Yes I guess it should explicitly pass all arguments to image(), which it doesn’t do…
Feel free to suggest a fix :slight_smile: Alternatively, just use an array type that carries both data and arbitrary axis ranges in one object:

using AxisKeysExtra

A = KeyedArray(rand(60, 60), x=range(0..1, length=60), y=range(0..1, length=60))
imagealpha(
	A;
	alpha=A .^ 1.5,
    colormap = :viridis,
    interpolate = false,
)

I personally didn’t even notice this limitation of imagealpha, simply because I tend to use KeyedArrays whenever makes sense.
