DevKit.Screenshot.Avalonia.Sharp

Main-window screenshot capture for Avalonia apps — a one-liner CI hook plus a programmatic IScreenshot service. Built for CI pipelines, visual testing and dev tooling.

Quick start

public override void OnFrameworkInitializationCompleted()
{
    if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
    {
        var args = desktop.Args ?? [];
        var options = ScreenshotArgs.ParseAndRemove(ref args);   // strips --devkit-screenshot…

        desktop.MainWindow = new MainWindow();
        desktop.AttachScreenshot(options);   // captures once the window opens and renders
    }

    base.OnFrameworkInitializationCompleted();
}

Run your app:

MyApp.exe --devkit-screenshot artifacts/shot.png --devkit-screenshot-exit --devkit-screenshot-delay 300
MyApp.exe --devkit-screenshot-clipboard --devkit-screenshot-exit

The window opens, renders, waits the settle delay, saves the PNG and (with -exit) shuts down. On failure the error goes to stderr and the app exits with code 70 — return the lifetime's exit code from Main to propagate it:

[STAThread]
public static int Main(string[] args) => BuildAvaloniaApp().StartWithClassicDesktopLifetime(args);

Without the CLI switch the hook is a no-op — ship it in production code freely.

Programmatic use

services.AddScreenshot();                    // registers IScreenshot

var result = await screenshot.CaptureMainWindowAsync("shot.png");
// result.OutputPath, result.PixelWidth, result.PixelHeight

await screenshot.CaptureMainWindowToClipboardAsync();
// result.CopiedToClipboard == true

Capture a subtree (panel, terminal surface, …)

await VisualScreenshotCapture.CopyToClipboardAsync(myBorder);
var bitmap = await VisualScreenshotCapture.CaptureAsync(myBorder);

Subtree capture flattens transparency by default so clipboard and file consumers that do not composite PNG alpha still show content. Opt out with new VisualCaptureOptions { FlattenTransparency = false } or supply an explicit Background brush.
