PrintDocument只打印我的JPG文件的一部分

我创建了一个允许用户打印多个jpg文件的应用程序。所以我直接发送我的打印请求,如下所示:

 if (existfile == true)
                {
                    PrinterSettings a=new PrinterSettings();
                    PrintDocument pd = new PrintDocument();
                    IEnumerable<PaperSize> size = a.PaperSizes.Cast<PaperSize>();
                    PaperSize a4 = size.First<PaperSize>(i => i.Kind == PaperKind.A4);
                    pd.DefaultPageSettings.Landscape = true;
                    pd.DefaultPageSettings.PaperSize = a4;
                    pd.PrintPage += PrintPage;
                    pd.Print();
                }

打印功能:

   private void PrintPage(object o, PrintPageEventArgs e)
        {
            System.Drawing.Image img = System.Drawing.Image.FromFile(CurrentAddress);
            Point loc = new Point(100, 100);
            e.Graphics.DrawImage(img, loc);
        }

但是这段代码只打印了我图像的某些部分,而不是全部。我想打印它们scale to fit。我怎么能这样做?

这可能会解决问题。

e.Graphics.DrawImage(img, e.MarginBounds);

e.Graphics.DrawImage(img, e.PageBounds);

ev.Graphics.DrawImage(Image.FromFile("C:\\My Folder\\MyFile.bmp"), ev.Graphics.VisibleClipBounds);
