In this step you'll use code to add content to the document and format it.

1. Open the MainPage.xaml.cs file associated with your application. Add the following using statements to the top of your page:

C#	Copy Code
using C1.Xaml.Pdf; using Windows.UI; using Windows.Storage; using Windows.Storage.Pickers; using Windows.UI.Popups;

2. Create a C1PdfDocument by adding the following code directly below the page constructor:

C#	Copy Code
C1PdfDocument pdf;

3. Directly below the InitializeComponent() method, add a MainPage_Loaded method and create a new C1PdfDocument:

   

C#	Copy Code
this.Loaded += MainPage_Loaded; pdf = new C1PdfDocument(PaperKind.Letter); pdf.Clear();

4. Then add the MainPage_Loaded event:

C#	Copy Code
async void MainPage_Loaded(object sender, RoutedEventArgs e) { progressRing.IsActive = true; CreateDocumentText(pdf); await c1PdfViewer1.LoadDocumentAsync(PdfUtils.SaveToStream(pdf)); progressRing.IsActive = false; }

5. Below the added event, add the code that will add content to your Pdf document and format it:

C#

Copy Code

static void CreateDocumentText(C1PdfDocument pdf) { // use landscape for more impact pdf.Landscape = true; // measure and show some text var text = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmood tempor incididunt ut labore magna aliqua. Ut enim ad minim veniam, quis nostrud excecitation ullmanco laboris. nisi ut alquip ex ea commodo consequat."; var font = new Font("Segoe UI Light", 14, PdfFontStyle.Italic); // create StringFormat used to set text alignment and line spacing var fmt = new StringFormat(); fmt.LineSpacing = -1.5; // 1.5 char height fmt.Alignment = HorizontalAlignment.Center; // measure it var sz = pdf.MeasureString(text, font, 72 * 3, fmt); var rc = new Rect(pdf.PageRectangle.Width / 2, 72, sz.Width, sz.Height); rc = PdfUtils.Offset(rc, 110, 0); // draw a rounded frame rc = PdfUtils.Inflate(rc, 0, 0); pdf.FillRectangle(Windows.UI.Colors.Teal, rc, new Size(0, 0)); //pdf.DrawRectangle(new Pen(Colors.DarkGray, 5), rc, new Size(0, 0)); rc = PdfUtils.Inflate(rc, -10, -10); // draw the text pdf.DrawString(text, font, Windows.UI.Colors.White, rc, fmt); // now draw some text rotating about the center of the page rc = pdf.PageRectangle; rc = PdfUtils.Offset(rc, rc.Width / 2.2, rc.Height / 2.5); // build StringFormat used to rotate the text fmt = new StringFormat(); // rotate the string in small increments var step = 6; text = "C1PDF works in Windows Runtime!"; for (int i = 0; i <= 360; i += step) { fmt.Angle = i; font = new Font("Courier New", 8 + i / 30.0, PdfFontStyle.Bold); byte b = (byte)(255 * (1 - i / 360.0)); pdf.DrawString(text, font, Windows.UI.Color.FromArgb(0xff, b, b, b), rc, fmt); } }

6. Add the code that will call the Save method you'll add in a separate code file:

C#	Copy Code
private void btnSave_Click(object sender, RoutedEventArgs e) { PdfUtils.Save(pdf); }
