在C＃中将另一张图像打印到第二页 [英] Print another image to the second page in C#

问题描述

如何在打印文档的第二页中打印第二张图像..

how do i print the second image in the second page of the print document..

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        Graphics graphics = e.Graphics;

        Image bgFront = ((PictureBox)pictureBox_IDFront).Image;
        e.Graphics.DrawImage(bgFront, 0, 0, 212, 337);


        Image bgBack = ((PictureBox)pictureBox_IDBack).Image;
        e.Graphics.DrawImage(bgBack, 212, 0, 212, 337);
    }

我想将第二张图片打印到另一页。我只需要2页就可以了。正面和背面的图像。每个页面包含一些像这样的字符串用于第二页。返回页面。

i want to print the second image to another page. i will only need 2 pages for this. the front and the back image. each pages includes some string like this is for the second page. the back page.

e.Graphics.DrawString("Employee Information", printFont, Brushes.Black, y, x);
        x = x + (printFont.Size + spacing);
        e.Graphics.DrawString("Name: " + this.label_FullName.Text, printFont, Brushes.Black, y, x);
        x = x + (printFont.Size + spacing);
        e.Graphics.DrawString("Address: ", printFont, Brushes.Black, y, x);

非常感谢你的帮助。

如果e.HasMorePages为True，PrintPage路由会被打印一次，并且会继续打印



您需要在该例程之外声明的页面计数变量您更新并且 - 如果pagecount = 2则e.HasMorePages = False



您也可以使用相同的变量来决定要打印的图像。

Have a quick read of: An absolute beginner's guide to printing in .NET[^]

The PrintPage routing gets called once for every page printed and will continue on if e.HasMorePages is True

You need a page count variable declared outside of that routine that you update and - if pagecount = 2 then e.HasMorePages = False

You can also use that same variable to decide what image to print.

当您进行多页打印时，由您决定随时打印哪个页面，如MSDN中所示：如何：Pri Windows窗体中的多页文本文件 [ ^ ]

该示例从字符串打印，并在下次从中删除打印部分，但它与图像的原理完全相同：保留一个类级别变量，告诉您所在的页面，或者设置要打印的图像集合，并在打印时从集合中删除每个图像。

When you do multipage printing, it's up to you to decide which page you are printing at any moment, as showed in MSDN: How to: Print a Multi-Page Text File in Windows Forms[^]
That example prints from a string, and removes the printed part from it for next time, but it's exactly the same principle with images: either keep a class level variable which tells you which page you are on, or set up a collection of images to print and remove each from the collection when you print it.
