Bug in GetThumbnailImage method?

The image loads halfway or so.... with the last loaded vertical line clipped... (see attached picture)...

What's the deal with this?

VB Code:

Dim r As Drawing.Image
        r = Drawing.Image.FromStream(ms)
        Dim dummyCallBack As System.Drawing.Image.GetThumbnailImageAbort
        dummyCallBack = New _
         System.Drawing.Image.GetThumbnailImageAbort(AddressOf DummyImagePointer)
        Dim thumbNailImg As System.Drawing.Image
        Dim g As Drawing.Size
        g = r.PhysicalDimension.ToSize
        Dim c As Double
        c = g.Width / 100
        thumbNailImg = r.GetThumbnailImage(100, Convert.ToInt32(g.Height / c), dummyCallBack, IntPtr.Zero)
 
        f.PictureBox1.Image = thumbNailImg
 
'this function forces continued execution of the getThumnailImage function
Public Function DummyImagePointer() As Boolean
        Return False
End Function

i think it has something to do with the "return false" callback..try puting "return true" or just use the other overloaded function that doesnt use the callback (i think there's one that doesnt use it right?)

I investigated that possibility... didn't make a difference. You'll probably hate yourself for even replying, because no,its not a bug, and ahem, let's just say it has to do with a certain memoryStream that was obtained from a networkStream that wasn't sending the entire picture over the network... for some reason, my send/receive code breaks (as in fails to due what it should) at around 65k images... something to do with buffersizes...

But since I was planning on sending the images as thumbnails anyway, I just implemented it on the server side, and well, that'll keep it in check...

Sorry for wasting your time, lol...

something like u said happened to me once but as you didnt say that you got the image over network i didnt say a thing about it
