Need help in creating pdf with images


I have a requirement wherein I have to create PDF out of the framework elements. Say, I have labels, textboxes. I have to capture an image for the same and insert it into a PDF. As I came to know, only jpegs are supported, so I tried creating a jpeg for the control and then creating a pdf. Here is the code I am using:

public sealed partial class CustomControl: UserControl
 public async Task Print(StorageFile file,)
            //Creates a new PDF document.
            PdfDocument doc = new PdfDocument();

            //Adds a page to the document.
            PdfPage page = doc.Pages.Add();

            //Creates Pdf graphics for the page.
            PdfGraphics g = page.Graphics;

            //Creates a solid brush.
            PdfBrush brush = new PdfSolidBrush(new PdfColor(255,0,0));

            //Sets the font.
            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12);

            PdfImage image = new PdfBitmap(await CreateBitmap(this));

            g.DrawImage(image, new System.Drawing.PointF(10, 10));

            await doc.SaveAsync(file);

        async public Task<System.IO.Stream> CreateBitmap(FrameworkElement element)
            // render element to image (WinRT)
            var renderTargetBitmap = new RenderTargetBitmap();
            await renderTargetBitmap.RenderAsync(element);
            var wb = new WriteableBitmap(renderTargetBitmap.PixelWidth, renderTargetBitmap.PixelHeight);
            (await renderTargetBitmap.GetPixelsAsync()).CopyTo(wb.PixelBuffer);
            var rect = new Rect(0, 0, renderTargetBitmap.PixelWidth, renderTargetBitmap.PixelHeight);

            StorageFolder folder = Windows.Storage.ApplicationData.Current.LocalFolder;

            await wb.SaveToFile(folder, "test1.jpeg");
            StorageFile file = await Windows.Storage.ApplicationData.Current.LocalFolder.GetFileAsync("test1.jpeg");
            Stream stream = await file.OpenStreamForReadAsync();
            return stream;

But this still gives me the same error that jpeg is only supported. Can you please let me know where I am going wrong.
