When using SkCanvasView inside Blazor in Maui, does every canvas action require interop?

[ToolmakerSteve]

Using SkiaSharp.Views.Blazor.SKCanvasView, as a Razor component inside the BlazorWebView of a Maui Blazor Hybrid app, how exactly do C# canvas operations (e.g. canvas.DrawCircle) render to the Skia canvas?

My understanding is:

• C# code is running native on the device.
• Razor components live within the HTML hierarchy inside the BlazorWebView, which is a native WebView control on each platform.
• Communication between the native C# and a Razor component (or any HTML control) require interop.

Is that correct so far?

If so, that sounds like canvas.DrawCircle would require an interop each frame.
A lot of those would thus be a performance issue?

For performance, do we need to rewrite our code to put as much as possible into an SKPictureRecorder?
(So that we can render it with a single canvas operation.)

If we change from SKCanvasView to SKGLView, will that be roughly the same, in terms of how code should be rewritten for the sake of performance? Are there any additional considerations when using GL?
