resizing images 2

[mjd3000]

I am working from this example to resize an image :

http://aspnet.4guysfromrolla.com/articles/012203-1.2.aspx

I have converted most of the code to C# :

Response.Clear();
Response.ContentType = "image/jpeg";

System.Drawing.Image image = retrieveImage(strEncodedImage);

System.Drawing.Image.GetThumbnailImageAbort dummyCallback;

dummyCallback = new System.Drawing.Image.GetThumbnailImageAbort(new EventHandler(ThumbnailCallback));

System.Drawing.Image thumb;

thumb = image.GetThumbnailImage(600, 350, dummyCallback, IntPtr.Zero);

thumb.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);

But I'm not sure what to do with this :

Function ThumbnailCallback() as Boolean
Return False
End Function

Can anybody help?

Your code would be something like this:

[COLOR=green]
// This is the main method.
[/color]
void resizeImage()
{
  Image img = retrieveImage(strimg);
  Image thumb = image.GetThumbnailImage(600,350, new GetThumbnailImageAbort(ThumbnailCallback));
  thum.Save(...);
}
[COLOR=green]
// This is a callback method required by the Image.GetThumbnailImage() method.
[/color]
bool ThumbnailCallback()
{  return false;  }

This is untested, wrote it off the top of my head.
