Thank you very much...


now, i have to do the opposite...   8)
i got a PixBuf loaded from a file, and scalled. (the reason why i open
it as a pixbuf... the ScaleSimple...)

this pixbuf, i need to save it in my database. im doing this with
DbType.Binary, and try to change it to typeof(Pixbuf) but obviously the
database doesnt know how to handle that:

System.InvalidCastException: Can't cast System.MonoType into any valid
DbType.


How do i transform my Pixbuf to a byte[] ?




Thanks!
