Drawing Framework Element Objects

You can use the C1PDFDocument.DrawElement method to draw the framework element objects like the following:

To write the code in Visual Basic:

Private Sub CreateVisualTree(pdf As C1PdfDocument, targetElement As FrameworkElement)

' set up to render

Dim font = New Font("Courier", 14)

' go render

Dim firstPage = True

For Each stretch__1 As Stretch In New Stretch() {Stretch.Fill, Stretch.None, Stretch.Uniform, Stretch.UniformToFill}

' add pagebreak

If Not firstPage Then

pdf.NewPage()
End If

firstPage = False

' set up to render

Dim alignment = ContentAlignment.TopLeft

Dim rc = PdfUtils.Inflate(pdf.PageRectangle, -72, -72)

' render element

pdf.DrawString("Element as VisualTree, Stretch: " + stretch__1.ToString(), font, Colors.Black, rc)

rc = PdfUtils.Inflate(rc, -20, -20)

pdf.DrawElement(targetElement, rc, alignment, stretch__1)
Next

End Sub

To write the code in C#:

void CreateVisualTree(C1PdfDocument pdf, FrameworkElement targetElement)

{

// set up to render

var font = new Font("Courier", 14);

// go render

var firstPage = true;

foreach (Stretch stretch in new Stretch[] { Stretch.Fill, Stretch.None, Stretch.Uniform, Stretch.UniformToFill })

{

// add pagebreak

if (!firstPage)

{

pdf.NewPage();

}

firstPage = false;

// set up to render

var alignment = ContentAlignment.TopLeft;

var rc = PdfUtils.Inflate(pdf.PageRectangle, -72, -72);

// render element

pdf.DrawString("Element as VisualTree, Stretch: " + stretch.ToString(), font, Colors.Black, rc);

rc = PdfUtils.Inflate(rc, -20, -20);

pdf.DrawElement(targetElement, rc, alignment, stretch);

}
