How to convert block of html to an image (e.g. jpg) in asp.net

问题

I would like to convert html (for example, a table) to an image and save it as a .jpg file. And, if that table is displayed within a web page along with other elements, I only want to get that specific table and save it as an image.

Is this possible using asp.net?

thanks

回答1:

I think this is a rendering issue and completely depends upon what browser rendering your HTML.

But this the closest thing I could get you using GDI+ and WebBrowser control from CodeProject.

Let me know whether it helped you or not!
