help:simple thumbnail doesnt work..

[eramgarden]

I followed the example on this website:

http://www.eggheadcafe.com/articles/20030515.asp

To convert a HUGE Tiff to a samller JPeg image .. to reduce the dimenstions ....it converts the image to JPeg but still the weidth and height remain the same...it does NOT reduce the height and weidth to a smaller image..
What am I missing??
This is what I have:

Dim strFileToConvert As String


        strFileToConvert = "C:\IP\W0008-01-01.tif.jpeg"
        Initialize the bitmap object by supplying the image file path
        Dim b As New Bitmap(strFileToConvert)

        Dim g As Graphics = Graphics.FromImage(b)

        g.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
        g.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
        g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
        Dim newrec As Rectangle = New Rectangle(0, 0, 50, 50)
        g.DrawImage(b, newrec)
        b.Save(strFileToConvert & ".jpeg", System.Drawing.Imaging.ImageFormat.Jpeg)

        g.Dispose()

Use the GetThumbnailImage method of the Bitmap object to return a scaled image.
