此示例显示如何在 表页面上放置水印，页面上的水印可以是文本，表达的结果或图像。水印也可以放在页面的任何位置。在此示例中，我们将添加文本水印。为此，我们使用 表的绘图页面事件：

static void Main(){    StiPage.PagePainting += new StiPagePaintEventHandler(OnPagePainting);    StiPage.PagePainted += new StiPagePaintEventHandler(OnPagePainted);    Application.EnableVisualStyles();    Application.Run(new Form1());}private static void OnPagePainting(StiPage sender, StiPagePaintEventArgs e){    if (copyrightPosition == Position.Behind)    {        StiPage page = sender as StiPage;        DrawCopyright(page, e);    }}private static void OnPagePainted(StiPage sender, StiPagePaintEventArgs e){    if (copyrightPosition == Position.Front)    {        StiPage page = sender as StiPage;        DrawCopyright(page, e);    }}

渲染水印的方法如下：

private static void DrawCopyright(StiPage page, StiPagePaintEventArgs e){    if (e.IsPrinting && (!printer))return;    if (e.IsDesigning && (!designer))return;    if ((!e.IsDesigning) && (!e.IsPrinting) && (!preview))return;    Rectangle rect = e.FullRectangle;    if (rectClient)rect = e.ClientRectangle;    using (Font font = new Font("Arial", 20 * (float)page.Zoom))    using (StringFormat sf = new StringFormat())    {        switch (copyrightPlace)        {            case Place.TopLeft:                sf.Alignment = StringAlignment.Near;                sf.LineAlignment = StringAlignment.Near;                break;            case Place.TopRight:                sf.Alignment = StringAlignment.Far;                sf.LineAlignment = StringAlignment.Near;                break;            case Place.Center:                sf.Alignment = StringAlignment.Center;                sf.LineAlignment = StringAlignment.Center;                break;            case Place.BottomLeft:                sf.Alignment = StringAlignment.Near;                sf.LineAlignment = StringAlignment.Far;                break;            case Place.BottomRight:                sf.Alignment = StringAlignment.Far;                sf.LineAlignment = StringAlignment.Far;                break;        }        e.Graphics.DrawString(copyrightString, font, Brushes.Red, rect, sf);    }}

示例代码的结果如下图所示：
