Watermark are not aligned

    I have some problem using Watermark.

    WPPDFPrinter1.Filename := 'c:\test.pdf';
    WPPDFPrinter1.BeginDoc;
    WPPDFPrinter1.StartWatermark('prova',595,842,72,72);
    WPPDFPrinter1.Canvas.Font.Size := 12;
    WPPDFPrinter1.Canvas.TextOut(72,72,'Testo su watermark PROVA');
    WPPDFPrinter1.EndWatermark;
    WPPDFPrinter1.StartPage(595,842,72,72,0);
    WPPDFPrinter1.Canvas.Font.Size := 12;
    WPPDFPrinter1.Canvas.MoveTo(0,0);
    WPPDFPrinter1.UseWatermarkEx('prova',595,842,0);
    WPPDFPrinter1.Canvas.TextOut(72,72,'Testo Normale');
    WPPDFPrinter1.EndPage;
    WPPDFPrinter1.EndDoc;

    Why isn't text overlapped?
    I have same problem using PDF file as watermark

    I have lastest version of WPdf (2.5.0)

    Best regarts and happy new year
