Bogue

If the MapView.SetViewpointCenterAsync() method is called before MapView.ExportImageAsync(), the exported image is an incomplete display.

Informations supplémentaires

The current behavior is by-design. ExportImageAsync exports the view as-is and does not wait for the rendering to complete. Additional code should be added to wait for draw status to report that rendering is complete before calling ExportImageAsync. e.g. ``` private static Task WaitForRenderCompleteAsync(MapView mapview) { TaskCompletionSource tcs = new TaskCompletionSource(); if (mapview.DrawStatus == DrawStatus.Completed) tcs.SetResult(null); else { EventHandler h = null; h = (s, e) => { if (e.Status == DrawStatus.Completed) { mapview.DrawStatusChanged -= h; tcs.SetResult(null); } }; mapview.DrawStatusChanged += h; } return tcs.Task; } ```

Solution de contournement

Adding Task.Delay() with 1000 milliseconds works:await MyMapView.SetViewpointCenterAsync(_londonCoords, 1000);// Adding Task.Delay() works as belowawait Task.Delay(1000);imageView.Source = await RuntimeImageExtensions.ToImageSourceAsync(await MyMapView.ExportImageAsync());
