+# How to save a `Figure` with transparency
+
+## CairoMakie
+
+In CairoMakie, set the background color to `:transparent` (converts to `RGBAf(0, 0, 0, 0)`) to get a fully transparent background.
+In the following examples, I use a partially transparent blue because a transparent background is indistinguishable from the usual white on a white page.
+
+\begin{examplefigure}{svg = true}
+```julia
+using CairoMakie
+CairoMakie.activate!() # hide
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+```
+\end{examplefigure}
+
+## GLMakie
+
+For technical reasons, GLMakie's color buffer does not have an alpha component:
+
+\begin{examplefigure}{}
+```julia
+using GLMakie
+GLMakie.activate!() # hide
+Makie.inline!(true) # hide
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+```
+\end{examplefigure}
+
+
+With the following trick you can still save an image with transparent background.
+It works by setting two different background colors and calculating the foreground color with alpha from the difference.
+
+```julia:transparent-glmakie
+using GLMakie
+GLMakie.activate!() # hide
+Makie.inline!(true) # hide
+
+function calculate_rgba(rgb1, rgb2, rgba_bg)::RGBAf
+    rgb1 == rgb2 && return RGBAf(rgb1.r, rgb1.g, rgb1.b, 1)
+    c1 = Float64.((rgb1.r, rgb1.g, rgb1.b))
+    c2 = Float64.((rgb2.r, rgb2.g, rgb2.b))
+    alphas_fg = 1 .+ c1 .- c2
+    alpha_fg = clamp(sum(alphas_fg) / 3, 0, 1)
+    alpha_fg == 0 && return rgba_bg
+    rgb_fg = clamp.((c1 ./ alpha_fg), 0, 1)
+    rgb_bg = Float64.((rgba_bg.r, rgba_bg.g, rgba_bg.b))
+    alpha_final = alpha_fg + (1 - alpha_fg) * rgba_bg.alpha
+    rgb_final = @. 1 / alpha_final * (alpha_fg * rgb_fg + (1 - alpha_fg) * rgba_bg.alpha * rgb_bg)
+    return RGBAf(rgb_final..., alpha_final)
+end
+
+function alpha_colorbuffer(figure)
+    scene = figure.scene
+    bg = scene.backgroundcolor[]
+    scene.backgroundcolor[] = RGBAf(0, 0, 0, 1)
+    b1 = copy(colorbuffer(scene))
+    scene.backgroundcolor[] = RGBAf(1, 1, 1, 1)
+    b2 = colorbuffer(scene)
+    scene.backgroundcolor[] = bg
+    return map(b1, b2) do b1, b2
+        calculate_rgba(b1, b2, bg)
+    end
+end
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+
+save(joinpath(@OUTPUT, "transparent.png"), alpha_colorbuffer(f)) # hide
+save("transparent.png", alpha_colorbuffer(f))
+```
