hidedecorations!() and backgroundcolor not supported for ::GeoAxis

[Zetison]

It seems to me that hidedecorations! and backgroundcolor is not provided for ::GeoAxis?

This example then fails.

Hidedecorations will be supported by #207, backgroundcolor can be added after that though it's a bit more difficult.

[Zetison]

Does it exist a workaround for the backgroundcolor?

[asinghvi17]

You could set ga.scene.backgroundcolor, but that would cover the area of the scene, not just the geoaxis. If your entire figure has the same background color then it might be worth it though.

I suspect not, but it does not work with the following example (where I want the ocean to be colored :lightblue1)?

using GLMakie, GeoMakie
fig = Figure(; size=(1920, 1080))

gridlayout1 = fig[1, 1:2] = GridLayout()
gridlayout2 = fig[2:4, 1] = GridLayout()
gridlayout3 = fig[2, 2] = GridLayout()
gridlayout4 = fig[3, 2] = GridLayout()
gridlayout5 = fig[4, 2] = GridLayout()

rowsize!(fig.layout, 3, Relative(0.55))
source = "+proj=merc +lon_0=0 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs"
dest = "+proj=merc +lon_0=0 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs"
ax1 = GeoMakie.GeoAxis(gridlayout2[1, 1]; source=source, dest=dest)
land = GeoMakie.land();
coastlns = poly!(
    ax1,
    land;
    color=:honeydew,
    colormap=:dense,
    strokecolor=:gray50,
    strokewidth=0.5,
    inspectable=false,
)
ax2 = Axis(gridlayout3[1, 1]; alignmode=Outside(), tellheight=false, tellwidth=false)
ax3 = Axis(gridlayout4[1, 1]; alignmode=Outside(), tellheight=false, tellwidth=false)

x = range(0, 1, 100)
lines!(ax2, x, sin.(2x))
lines!(ax3, x, sin.(3x))
ax1.scene.backgroundcolor = parse(Colorant, :lightblue1)

for me it worked to pass the backgroundcolor to the Figure initialization. Not the best solution but I think it will do what you want.

This sets the background color for the entire figure blue (also around the ax2 and ax3 axis), and I only want it for the ax1 object (such that I get a map with a nice blue ocean).

[Zetison]

An ugly fix could be to implement the backgroundcolor option as

ocean_coords = [(180, -90), (-180, -90), (-180, 90), (180, 90)]
ocean = poly!(ax, ocean_coords, color = :lightblue1, strokewidth=0.5, strokecolor=:gray50)
Makie.translate!(ocean, 0, 0, -100)
