I try to save the UI elements into an image file. but we have More UI elements(like 100 list of rows). So the image quality is very poor. Is there any possibility to convert the UI elements into multiple images or get the image with High Quality please share some suggestions for this.
I have tried to save the image file using the below code:
public async Task GenereateImage(UIElement root) { RenderTargetBitmap renderTargetBitmap1 = new RenderTargetBitmap(); await renderTargetBitmap1.RenderAsync(root, (int)root.RenderSize.Width, (int)root.RenderSize.Height); var pixelBuffer1 = await renderTargetBitmap1.GetPixelsAsync(); var disply = DisplayInformation.GetForCurrentView(); var savePicker = new FileSavePicker(); savePicker.DefaultFileExtension = ".png"; savePicker.FileTypeChoices.Add(".png", new List<string> { ".png" }); savePicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary; savePicker.SuggestedFileName = "snapshot.png"; // Prompt the user to select a file var saveFile = await savePicker.PickSaveFileAsync(); // Verify the user selected a file if (saveFile == null) return; // Encode the image to the selected file on disk using (var fileStream = new Windows.Storage.Streams.InMemoryRandomAccessStream()) { var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.PngEncoderId, fileStream); encoder.SetPixelData( BitmapPixelFormat.Bgra8, BitmapAlphaMode.Ignore, (uint)renderTargetBitmap1.PixelWidth, (uint)renderTargetBitmap1.PixelHeight, DisplayInformation.GetForCurrentView().LogicalDpi, DisplayInformation.GetForCurrentView().LogicalDpi, pixelBuffer1.ToArray()); await encoder.FlushAsync(); } } And the result image be like is:
ContainerFromIndexmethod to get each listviewitem and render them separately?
