以横向打印图像？

我正在将控件转换为位图并打印它：

using (MemoryStream ms = new MemoryStream()) { chart1.SaveImage(ms, ChartImageFormat.Bmp); Bitmap bm = new Bitmap(ms); PrintDocument doc = new PrintDocument(); doc.PrintPage += (s, ev) => { ev.Graphics.DrawImage(bm, Point.Empty); // adjust this to put the image elsewhere ev.HasMorePages = false; }; doc.Print(); } 

如何指定以横向打印？

Answer 1

 doc.DefaultPageSettings.Landscape = true;

Answer 2

通过PrintDocument.DefaultPageSettings可浏览属性。

 PrintDocument.DefaultPageSettings.Landscape = true; 

因此，对于您的代码示例，这将是：

 doc.DefaultPageSettings.Landscape = true;
