[FR] Implement a dpi option.

[Datseris]

Would be very nice to get a dpi argument to Makie.save.

Makie.save("static_billiard_plot.png", scene, dpi = 600)

doesn't work. But it is really a big pain to simple "increase the resolution of the scene", because I must manually adjust every single text size.

And if not, when I save it into file it really looks crappy at low resolutions...

if your plot is 2d, cairomakie should be able to handle it now, and it has the argument px_per_unit for png scaling and pt_per_unit for vector scaling. Can you try that?

[Datseris]

Sure, I will try it at night, thanks for letting me know. To switch backends do I simply write using CairoMakie after using Makie?

[asinghvi17]

Yep, that should be sufficient. You can switch between backends by using CairoMakie.activate!() or GLMakie.activate!().

[asinghvi17]

We just released a new version of CairoMakie, by the way - so you should be sure to upgrade before you try this out. (It fixes a bunch of things related to markers...)

Can you give an example how to use pt_per_unit? What does pt_per_unit mean? Thanks!

[SimonDanisch]

px_per_unit is now supported for all backends as of #3113
