Ejemplos

En el ejemplo siguiente se muestra cómo utilizar esta clase para escalar un elemento visual de forma que quepa dentro de los márgenes del papel en el que se va a imprimir.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()
