Description

soFromBeginning	Offset is from the beginning of the BLOB field. Seek moves to the position Offset. Offset must be >= 0.
soFromCurrent	Offset is from the current position in the BLOB field. Seek moves to Position + Offset.
soFromEnd	Offset is from the end of the BLOB field. Offset must be <= 0 to indicate a number of bytes before the end of the BLOB.

Seek returns the new value of the Position property, the new current position in the BLOB field.
