Cutout of Projection / Correct handling of limits

[yum-yab]

For my thesis I wanted to use Albers Equal Area Projection or Orthographic projection, but unfortunately im not able to cut out my area of interest (Europe). I tried following along the Documentation provided here.

My code is the following:

using GLMakie, GeoMakie

fig = Figure()
ga1 = GeoAxis(fig[1, 1]; dest = "+proj=aea +lat_1=20 +lat_2=80 +lat_0=90 +lon_0=-25 +x_0=0 +y_0=0", limits=((-90, 40), (20, 80)))
ga2 = GeoAxis(fig[1, 2]; dest = "+proj=merc", limits=((-90, 40), (20, 80)))

ga3 = GeoAxis(fig[2, 1]; dest = "+proj=ortho +lat_0=50 +lon_0=-25", limits=((-90, 40), (20, 80)))
ga4 = GeoAxis(fig[2, 2]; dest = "+proj=ortho +lat_0=50 +lon_0=-25")


lines!(ga1, GeoMakie.coastlines())
lines!(ga2, GeoMakie.coastlines())
lines!(ga3, GeoMakie.coastlines())
lines!(ga4, GeoMakie.coastlines())

fig

And the result looks like:

I expected the orthographic and aea projection to cut out along lon/lat lines simiar to the merc projection in the top right, but the behaviour is pretty strange.
Without the limits the center and everything looks right to me (bottom right).

I'm also not able to fix the limits afterward because using xlims!(ga4, (-90, 40)) yields:

InexactError: trunc(Int64, Inf)

Am I doing something wrong? Or how could I achieve my goal?

Thanks for the help in advance!

I also tried to find how I could configure the GeoAxis for my needs but the corresponding page looks very weird, is that a bug? https://geo.makie.org/v0.7.2/examples/axis_config

Ah yeah, there are quite a few bugs and issues surrounding limits :D

I could possibly add a polygon that just "clips" everything outside certain lat/lon boundaries. That would probably solve your first issue but not the second.

Am a bit tied up right now but will write a full response later today!

Hi, thanks a lot for the help! Are there any updates on a workaround @asinghvi17 ?
