In your Silverlight application, please add the required assemblies in order to use Essential® PDF. Refer here for assemblies required.

Loading the document

The following code example illustrates how to load the file by using URI in Silverlight.

//Load the file as url

Uri uri = new Uri(@"\Resources\data\Sample.pdf", UriKind.Relative);

Stream docStream = ResourceManager.Load(uri);

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);

//Create booklet with two sides

PdfDocument document = PdfBookletCreator.CreateBooklet(loadedDocument, new SizeF(1000, 700), true);

MemoryStream stream = new MemoryStream();

//Save the document into memory stream

document.Save();

//close the documents

document.Close(true);

loadedDocument.Close(true);

public static class Extensions

{

public static void Save(this PdfDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

public static void Save(this PdfLoadedDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

}
'Load the file as url

Dim uri As New Uri("\Resources\data\Sample.pdf", UriKind.Relative)

Dim docStream As Stream = ResourceManager.Load(uri)

Dim loadedDocument As New PdfLoadedDocument(docStream)

'Create booklet with two sides

Dim document As PdfDocument = PdfBookletCreator.CreateBooklet(loadedDocument, New SizeF(1000, 700), True)

Dim stream As New MemoryStream()

'Save the document into memory stream

document.Save()

'close the documents

document.Close(True)

loadedDocument.Close(True)

Public Module Extensions

<System.Runtime.CompilerServices.Extension> _

Public Sub Save(ByVal document As PdfDocument)

Dim sfd As New SaveFileDialog() With {.DefaultExt = ".pdf", .Filter = "Adobe PDF Files(*.pdf)|*.pdf", .FilterIndex = 1}

If sfd.ShowDialog() = True Then

The following code example illustrates how to load the file by using stream in Silverlight.

//Load the file as stream

Stream docStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("sample.Resources.Data.sample.pdf");

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);

//Create booklet with two sides

PdfDocument document = PdfBookletCreator.CreateBooklet(loadedDocument, new SizeF(1000, 700), true);

MemoryStream stream = new MemoryStream();

//Save the document into memory stream

document.Save();

//close the documents

document.Close(true);

loadedDocument.Close(true);

public static class Extensions

{

public static void Save(this PdfDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

public static void Save(this PdfLoadedDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

}
'Load the file as stream

Dim docStream As Stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("sample.Resources.Data.sample.pdf")

Dim loadedDocument As New PdfLoadedDocument(docStream)

'Create booklet with two sides

Dim document As PdfDocument = PdfBookletCreator.CreateBooklet(loadedDocument, New SizeF(1000, 700), True)

Dim stream As New MemoryStream()

'Save the document into memory stream

document.Save()

'close the documents

document.Close(True)

loadedDocument.Close(True)

Saving the document

The following code example illustrates how to save the PDF document in Silverlight.

//Create a new document

PdfDocument document = new PdfDocument();

//Add a page

PdfPage page = document.Pages.Add();

//Create Pdf graphics for the page

PdfGraphics graphics = page.Graphics;

//Create a solid brush

PdfBrush brush = new PdfSolidBrush(Color.FromArgb(0, 0, 0, 0));

//Set the font

PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);

//Draw the text

graphics.DrawString("Hello world!", font, brush, new PointF(20, 20));

//Save the document

document.Save();

//Close the document

document.Close(true);

public static class Extensions

{

public static void Save(this PdfDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

public static void Save(this PdfLoadedDocument document)

{

SaveFileDialog sfd = new SaveFileDialog()

{

DefaultExt = ".pdf",

Filter = "Adobe PDF Files(*.pdf)|*.pdf",

FilterIndex = 1

};

if (sfd.ShowDialog() == true)

{

using (Stream stream = sfd.OpenFile())

{

document.Save(stream);

}

}

}

}
