是否可以使用ASP.NET MVC将视图（HTML）转换为图像？ [英] Is it possible to covert a view (HTML) into an image using ASP.NET MVC?

问题描述

我有一个要求，我想要转换包含HTML&要映像的CSS元素，然后将其传递给用户。我只是想知道C＃中是否有内置库可以动态生成图像？

请不要建议我使用第三方工具。



我尝试了什么：



我迷路了，我不知道从哪里开始。

I have a requirement where I want to convert a whole view which contains HTML & CSS elements to image and then pass it to the users. I am just wondering is there any builtin library in C# to generate images out of a view on the fly?
Please do not suggest me third party tools.

What I have tried:

I am lost and I don't know where to start from.

推荐答案

唯一的内置选项是在新线程中使用 WebBrowser 控件，如这个StackOverflow答案 [ ^ ]。 然而，这可能不会在ASP.NET站点中很好地工作。



为什么你如此反对第三方工具？例如， HTML-Renderer [ ^ ]看起来它可以完全满足您的需求，并且可以免费使用。 许可证 [ ^ ]看起来也很轻松。

The only built-in option would be to use the WebBrowser control in a new thread, as described in this StackOverflow answer[^]. However, that's probably not going to work very well in an ASP.NET site.

Why are you so opposed to third-party tools? For example, HTML-Renderer[^] looks like it would do exactly what you need, and is free to use. The license[^] looks pretty relaxed too.

你可以只进行一次屏幕截图相应调整图像大小？我在Google上找到了这个解决方案，几乎没有搜索。

You could just take a screen capture and adjust the image size accordingly? I found this solution on Google with little searching.

Rectangle bounds = Screen.GetBounds(Point.Empty);
using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
    using(Graphics g = Graphics.FromImage(bitmap))
    {
         g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
    }
    bitmap.Save("test.jpg", ImageFormat.Jpeg);
}
