reading image from website and resizing it and displaying

[nicklieb]

I am developing a little noddy windows form, and have an image place holder on the form.

it's really quite simple, where user enters a part number whihc is then displayed in a datagrid. When user click on a row, an image is then displayed in the placeholder of that part.

there are around 12,000 images all of different sizes, and I cannot really be bother to go through the laboruous task of resizing every image.

So what i want to do is to resize the image when they are read from the webserver:

 HttpWebRequest wReq = HttpWebRequest)WebRequest.Create(sURL);
HttpWebResponse wRes = (HttpWebResponse)(wReq).GetResponse();
 str = wRes.GetResponseStream();
Image outputimg = Image.FromStream(str);
 outputimg.Height = 213;
 outputimg.Width = 284;
 return outputimg;

this does not work, as it say the Height and width are read only... and I can't seem to fin how you can set the image dimension when they are output.

thanks in advance.

found what i need.. for you info:

                HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create(sURL);
                HttpWebResponse wRes = (HttpWebResponse)(wReq).GetResponse();
                str = wRes.GetResponseStream();
                   Size NewSize = new Size();
                NewSize.Height = strHeight;
                NewSize.Width = strWidth;
                Image.GetThumbnailImageAbort myCallback = new Image.GetThumbnailImageAbort(ThumbnailCallBack);
                Image outputimg = Image.FromStream(str).GetThumbnailImage(NewSize.Width, NewSize.Height, myCallback,IntPtr.Zero);

                
                return outputimg;

        public bool ThumbnailCallBack()
        {
            return false;
        }
