示例

下面的示例演示如何使用 DrawImageUnscaledAndClipped 方法。 若要运行此示例，请将其粘贴到 Windows 窗体中。 处理窗体的 Paint 事件，并从Paint事件处理方法调用 DrawImageUnscaled 方法，作为 ePaintEventArgs传递。

private void DrawImageUnscaled(PaintEventArgs e)
{
    string filepath = @"C:\Documents and Settings\All Users\Documents\" + 
        @"My Pictures\Sample Pictures\Water Lilies.jpg";
    Bitmap bitmap1 = new Bitmap(filepath);
    e.Graphics.DrawImageUnscaledAndClipped(bitmap1, new Rectangle(10,10,250,250));
}

Private Sub DrawImageUnscaled(ByVal e As PaintEventArgs) 
    Dim filepath As String = "C:\Documents and Settings\All Users\Documents\" _
        & "My Pictures\Sample Pictures\Water Lilies.jpg"
    Dim bitmap1 As New Bitmap(filepath)
    e.Graphics.DrawImageUnscaledAndClipped(bitmap1, _
        New Rectangle(10, 10, 250, 250))
End Sub
