Take a full, scrolling screenshot of a Blazor Hybrid app

Question

I am trying to find a way to take a screenshot of a Blazor Hybrid page that goes covers the area off screen as well.

I tried using html2canvas and was only able to get the current viewport.

I tried a DI injected native code that creates a bitmap from a webview, but was only able to get the visible display.

Has anyone got this working and has somewhere to point me to get the full, scrollable window?

You need to turn scrolling (overflow) off when you call html2canvas, turn back on after. this will cause a flicker.

a common browser approach is to have a print display popup. in Maui you do this by having the hosting app create a new webview, and passing markup to the new webview.
