Bitmap as a Image web control

[Ben]

Hi Ya,

quick question for you. Im a little new to web controls and im trying
to have a control that returns a bitmap image.

So i have created a web control library, added a control,

have the following

public class MyImage : System.Web.UI.WebControls.Image
{
Public Bitmap MyBitmap()
{
bitmap = new Bitmap(
300,
60,
PixelFormat.Format32bppArgb);
//........
// do some stuff
return bitmap
}


}


so how can i make it that the image control has the results from the
MyBitmap method?

or am i doing this totally wrong?

unlike a windows form, a image control in the browser is just a reference to
an external image and generate html like:

<img href="someimage.jpeg">

what you wnat to is create a page that reurns an image and have your web
control reference it:

<img href="myImage.aspx?id=<imageid>">

you can google for samples.

note: modern browsers (not IE) support inline images, in which case the you
base64 encode the image and include it in the url.
