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？
解决方法
doc.DefaultPageSettings.Landscape = true;
