如何在 A4 纸 c# 中打印大尺寸的图像

Question

我想在当前代码中以大尺寸从图片框中打印图像，并以原始尺寸打印， 我尝试了以下代码：

private void btnID_Click(object sender, EventArgs e)
        {
            PrintDialog pd = new PrintDialog();
            PrintDocument pdoc = new PrintDocument();
            pdoc.PrintPage += doc_printID;
            pd.Document = pdoc;
            if (pd.ShowDialog() == DialogResult.OK)
                pdoc.Print();


        }

        private void doc_printID(object sender, PrintPageEventArgs e)
        {
            Bitmap bm = new Bitmap(pictureIDIQAMA.Width, pictureIDIQAMA.Height);
            pictureIDIQAMA.DrawToBitmap(bm, new Rectangle(0, 0, pictureIDIQAMA.Width, pictureIDIQAMA.Height));
            e.Graphics.DrawImage(bm, 200,400);
            bm.Dispose();
        }

如何以至少两倍的原始尺寸打印更大尺寸的图像？

Answer 1

绘制页面边缘的图像

e.Graphics.DrawImage(bm, args.MarginBounds);

或

在页面的整个区域中绘制图像

e.Graphics.DrawImage(bm, args.PageBounds);
