Taking a screenshot in avalonia 11

[Varmod]

In my app I need the ability to take a screenshot, but I am unable figure out way how to do it.
I've found an older thread where it was recommended to use the the code from the TestBase class
https://github.com/AvaloniaUI/Avalonia/blob/release/11.0.0-rc1.1/tests/Avalonia.RenderTests/TestBase.cs
but I wasn't able to get that code running as many of the Compositor methods are internal.

Is there some other way to do it? or perhaps a way to directly access the last rendered frame?

The only important part is RenderTargetBitmap, which is still public.

            var pixelSize = new PixelSize((int)target.Width, (int)target.Height);
            var size = new Size(target.Width, target.Height);
            var dpiVector = new Vector(dpi, dpi);

            using (RenderTargetBitmap bitmap = new RenderTargetBitmap(pixelSize, dpiVector))
            {
                target.Measure(size);
                target.Arrange(new Rect(size));
                bitmap.Render(target);
                bitmap.Save(immediatePath);
            }

or perhaps a way to directly access the last rendered frame?

No.

Thank you for your quick reply, this solved the issue for me.

Could you please tell me where the target come from? How can I get the target object?

It is the control you want to render.

So if I want to get the screenshot of the whole screen, what should i pass?

Then you need to interop with your os. It's not related to Avalonia.
