asp.net mvc controller method that returns jpeg given parameter

Question

I would like to create a jpeg on the fly given some data from a database. The data is an array containing values which should be translated into a colour.

A asp.net mvc controller method should return a jpeg on the fly given one parameter.

This should be fairly straight forward. Could someone please point me to some existing code?

Thanks.

Here are a couple of possible options that may help you get started: I think you will porbably need an handler and then call the handler from your controller.

If you want this in pure mvc you can do this

Extending MVC: Returning an Image from a Controller Action

Another way is to create a HttpHandler that does that for you

HTTP Handlers for Images in ASP.NET

hope this helps

There is a tutorial on msdn on How to: Encode and Decode a JPEG Image.

Doing that in MVC3 is pretty similar, you just need a action in your controller like this:

public class YourController : Controller
{
    [HttpGet]
    public ImageResult GetImage(int whatever)
    {
        stream imageStream = yourJpgFactory.GetImage(whatever)
        return (imageStream)
    }
}

and in your view

 <img src="YourController/GetImage?whatever=42" />
