以橫向打印圖像？

Question

我正在將控件轉換為位圖並打印它：

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();
}

如何指定以橫向打印？

Answer 1

doc.DefaultPageSettings.Landscape = true;

Answer 2

通過PrintDocument.DefaultPageSettings可瀏覽屬性。

PrintDocument.DefaultPageSettings.Landscape = true;

因此，對於您的代碼示例，這將是：

doc.DefaultPageSettings.Landscape = true;
