从printdocument打印图像 [英] printing an image from printdocument

问题描述

亲爱的朋友，

在我的win窗体应用程序中，我想一次预览和打印许多图像.
因此，我将imageList用于多个图像，将printDocument和printPreviewDialog用于预览和打印.

我的代码如下:

Dear friends,

In my win form application i want to preview and print number of images at a time.
So i used a imageList for multiple images and a printDocument and a printPreviewDialog for preview and printing.

My code is as follows :

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
       {

           Image i = imageList1.Images[1];

           e.Graphics.DrawImage(i, 100, 50,i.Width, i.Height);


       }

但是当它永远不会占用原始图像的高度和宽度时.它减少了我图像的高度和宽度.

我怎么解决这个问题.我想保留图像的原始高度和宽度.

在此先感谢.

but when it never takes the original image height and width. It reduces the height and width of my image.

How can i solve this problem. I want to retain the original height and width of my image.

Thanks in Advance.
Shailesh.

What is the "original" size of an image? Both have resolution. You probably get the image in it''s original size in pixels. I suppose, your image''s resolution does not match that of the printer. And by the way a printer''s X and Y resolution is not the same in every case. Thus you have tho think in inches not in pixels, and recalculate the size.

您提供了非常短的代码示例.但是，我假设您需要预览一些图像然后再打印.看到这一点，有很多方便的图像处理命令，包括预览，打印图像，打印批处理等: http://www.artuxsoft. com/.

You provided very short code samples. However, I assume that you need to preview some images and then print them. See this one, there are a lot of convinient image processing commands including preview, print image, print batch and so on: http://www.artuxsoft.com/.
