Examples
The following example shows how to use this class to scale a visual element to fit within the margins of the paper on which it is to print.
/// <summary>
/// Returns a scaled copy of a given visual transformed to
/// fit for printing to a specified print queue.</summary>
/// <param name="v">
/// The visual to be printed.</param>
/// <param name="pq">
/// The print queue to be output to.</param>
/// <returns>
/// The root element of the transformed visual.</returns>
private Visual PerformTransform(Visual v, PrintQueue pq)
{
ContainerVisual root = new ContainerVisual();
const double inch = 96;
// Set the margins.
double xMargin = 1.25 * inch;
double yMargin = 1 * inch;
PrintTicket pt = pq.UserPrintTicket;
Double printableWidth = pt.PageMediaSize.Width.Value;
Double printableHeight = pt.PageMediaSize.Height.Value;
Double xScale = (printableWidth - xMargin * 2) / printableWidth;
Double yScale = (printableHeight - yMargin * 2) / printableHeight;
root.Children.Add(v);
root.Transform = new MatrixTransform(xScale, 0, 0, yScale, xMargin, yMargin);
return root;
}// end:PerformTransform()
