images using graphics class

[Gav]

Hi all,

I'm trying to create a bitmap and then use outputstream to display the
picture:

objBitmap.Save( Response.Output Stream, ImageFormat.Jpe g);

It doesn't give me any errors although the web page comes up with lots of
characters in the page instead of a picture... I then added:

Response.Conten tType= "image/jpeg";

I put this before the outputstream but it didn't make any difference, does
anybody know what I could be doing wrong?

Regards
Gav

base.Response.C learContent();
base.Response.C ontentType = "image/jpeg";
objBitmap.Save( Response.Output Stream, ImageFormat.Jpe g);
// Important to cancel page HTML rendering:
base.Response.E nd();

Gav,

Is your page buffered? I seem to remember that if it is not, then the
headers would be already written, and you could not change the content type.

Hope this helps.

Thanks for the help but I never could get this to work. I'm not sure why. I
think it may have something to do with the fact I'm trying to do it inside a
web user control (I'm not sure). But anyway I got around it by saving it to
a file and simply displaying the file.

Thanks again
Gav
