Answer 1

As I mentioned in my comment, your best bet is to opt for attempting to render HTML to an image.

Here is the link for a library that will allow your to render html to an image:

Here is code that does exactly what you're asking:

Now all you have left is to get the html, since I'm assuming you don't want this to render to the browser prior to generating this image - you should look into grabbing the rendered html from the aspx page on the server prior to returning it, and then just return the image. To render a page:

Sorted.

If you do not mind using a commandline tool you can have a look at wkhtmltopdf . The package include a wkhtmltoimage component that can be used to convert HTML to image, using

wkhtmltoimage [URL] [Image Path]

Codaxy also wrote a wkhtmltopdf c# wrapper available through the NuGet package manager. I'm not sure if the wkhtmltoimage component was included, but it should be easy enough to figure out how they wrap the wkhtml components.

         string root = Server.MapPath("~/");

            // clean up the path
            if (!root.EndsWith(@"\"))
                root += @"\";

            // make a folder to store the images in
            string fileDirectory = root + @"\images\a4en\";

            // create the folder if it does not exist
            if (!System.IO.Directory.Exists(fileDirectory))
                System.IO.Directory.CreateDirectory(fileDirectory);

        WriteBytesToFile( fileDirectory + + procad.ForSaleID + ".png", imageBytes);
