I know how to read the BMP thumbnail (there are some code here: http://forums.autodesk.com/t5/NET/Another-DWGThumb
Does anyone here have the code or some information about it?
I've found it:
fs.Seek(udtRec.lngStart, SeekOrigin.Begin) Using ms As New MemoryStream fs.CopyTo(ms, udtRec.lngStart) img = Image.FromStream(ms) End Using
