位图图像高度可能大于页面高度。在这种情况下，它应该打印成多页。
我尝试使用下面的代码来处理小型单页图像，但在行
处得到了OutOfMemoryExceptions.end() + 1使用
在ASP.NET MVC4控制器到服务器打印机中完成打印 e.Graphics.DrawImage(bm.Clone(new Rectangle(0,
pageHeight * (pageno - 1), bm.Width,
pageHeight),
System.Drawing.Imaging.PixelFormat.DontCare),
0, 0);
如何将图像打印到多个页面？
using System.Drawing.Printing;
using System.Drawing;
using System.IO;
byte[] bmp = bmp image created by wkhtmltoimage
var doc = new PrintDocument();
doc.PrinterSettings.PrinterName = "myprinter";
doc.PrintPage += new PrintPageEventHandler(ProvideContent);
pageHeight = doc.DefaultPageSettings.PaperSize.Height;
using (bm = new Bitmap(new MemoryStream(bmp)))
{
var lehti = (int)Math.Ceiling((double)(bm.Height / pageHeight));
doc.PrinterSettings.FromPage = 1;
doc.PrinterSettings.ToPage = lehti;
doc.PrinterSettings.MaximumPage = 1;
doc.PrinterSettings.MinimumPage = lehti;
pageno = 1;
doc.Print();
}
}
int pageno;
int pageHeight;
Bitmap bm;
void ProvideContent(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawImage(bm.Clone(new Rectangle(0, pageHeight * (pageno - 1), bm.Width, pageHeight), System.Drawing.Imaging.PixelFormat.DontCare),
0, 0);
}
有效，但只打印图像的上半部分。
