c# - 如何在 C# 中打印全尺寸图像

Question

我正在尝试用 C# 打印图像。它是由 Adob​​e Acrobat 从 PDF 创建的完整 8.5x11 大小的 tiff。当我使用下面的代码用 C# 打印它时，它垂直打印正确，但水平打印不正确，它被推过大约半英寸。我将图像的原点设置为 0,0。我错过了什么吗？

private FileInfo _sourceFile;
    public void Print(FileInfo doc, string printer, int tray)
    {
        _sourceFile = doc;
        PrintDocument pd = new PrintDocument();
        pd.PrinterSettings.PrinterName = printer;
        pd.DocumentName = _sourceFile.FullName;
        using (Image img = Image.FromFile(_sourceFile.FullName)) {
            if (img.Width > img.Height) {
                pd.DefaultPageSettings.Landscape = true;
            }
        }
        pd.PrintPage += PrintPage;
        foreach (PaperSource ps in pd.PrinterSettings.PaperSources) {
            if (ps.RawKind == tray) {
                pd.DefaultPageSettings.PaperSource = ps;
            }
        }
        pd.Print();
    }

    private void PrintPage(object o, PrintPageEventArgs e)
    {
        using (System.Drawing.Image img = System.Drawing.Image.FromFile(_sourceFile.FullName)) {
            Point loc = new Point(0, 0);
            e.Graphics.DrawImage(img, loc);
        }
    }

查看下面的代码以获得一个很好的示例，该代码来自下面的链接 Print Image in C#

        private void PrintImage()
        {
            PrintDocument pd = new PrintDocument();

            pd.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
            pd.OriginAtMargins = false;
            pd.DefaultPageSettings.Landscape = true;

            pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);


            printPreviewDialog1.Document = pd;
            printPreviewDialog1.ShowDialog();

            //pd.Print();
        }

        void pd_PrintPage(object sender, PrintPageEventArgs e)
        {
            double cmToUnits = 100 / 2.54;
            e.Graphics.DrawImage(bmIm, 100, 1000, (float)(15 * cmToUnits), (float)(10 * cmToUnits));
        }

        private void button5_Click(object sender, EventArgs e)
        {
            PrintImage();
        }
