Rotativa/Wkhtmltopdf图像不显示 [英] Rotativa / Wkhtmltopdf images not displaying

问题描述

我当前正在创建MVC 4 Web应用程序.

I am currently creating an MVC 4 web application.

我有一个动作，该动作的基本背景图像始终与箭头图像相同，箭头图像的角度根据动作中收集的信息而变化.

I have an action that has a base background image which is always the same then an arrow image which changes in degrees depending on the information that is collected within the action.

我使用

<img src="@Url.Action("trend-image", "NonReg_Reports")" alt="background" width="245" height="105" />

在被调用并且仅显示HTML网页时，此方法工作正常.它给了我HTML.

This works fine when it is called and is just displaying a HTML webpage. It gives me the HTML.

<img src="/nonreg-report/01495344/trend-image" alt="background" width="245" height="105">

然后，我使用Rotativa/Wkhtmltopdf将HTML页面转换为PDF.这将运行与上面相同的代码.

I am then using Rotativa / Wkhtmltopdf to convert this HTML page into a PDF. This runs the same piece of code as above.

问题是，如果使用上面的代码，我只会得到一个带有替代文本的白框.

The problem is I am just getting a white box with the alternative text in it if I use the code above.

如果我使用< img src =〜/Content/images/trend_back_medium.png" alt ="astuff"/> (这是我项目中的实际背景图片)，则效果很好.

If I use <img src="~/Content/images/trend_back_medium.png" alt="astuff" /> which is the actual background image in my project it works fine.

由于使用方法，上述代码中的图像无法保存在任何地方.我认为这是一个路径问题，但是尝试了许多不同的操作后，我仍然无法使它正常工作.

The image from the code above can not be saved anywhere due to how it is used. I am thinking that it is a path problem, but after trying lots of different things I can still not get it to work.

任何建议或帮助将不胜感激，谢谢.

Any suggestions or help would be greatly appreciated Thank you.

推荐答案

我遇到了同样的问题.正常的html视图可以显示图片，而pdf无法显示.我用Server.MapPath指向图片，没关系...

I had the same problem. Normal html view was ok with pictures, pdf was not display it. I used Server.MapPath to point to picture and it was ok...

<img src="@Server.MapPath("~/Folder/SubFolder/Subfolder/ImageName.png")" />

我希望这会有所帮助
