Sorry the code tag doesn't like vb.net code.Pearson Education, Inc., 221 River Street, Hoboken, New Jersey 07030, (Pearson) presents this site to provide information about Adobe Press products and services that can be purchased through this site. _NormalImage.GetThumbnailImage(Convert.ToInt32(_NewWidth), Convert.ToInt32(_NewHeight), _Callback, _ _NewHeight = _OriginalHeight / _OriginalWidth * MaximumSize _NewWidth = _OriginalWidth / _OriginalHeight * MaximumSize _Graphics.DrawImage(Input, 0, 0, Input.Width, Input.Height) _Graphics = Graphics.FromImage(_NormalImage) _NormalImage = New Bitmap(Input.Width, Input.Height) Public Function ToThumbnail(ByVal Input As Image, ByVal MaximumSize As Integer, Optional ByVal KeepAspectRatio As Boolean = True) As Imageĭim _Callback As Image.GetThumbnailImageAbort = Nothing ''' _Graphics.FillRectangle(Brushes.Blue, New Rectangle(0, 0, 100, 100)) ''' _Graphics = Graphics.FromImage(_Image) ''' If set false width and height will be the same else the highest number of width or height is used and the other is calculated accordingly.
