Here is some sample code showing how to use this method:

procedure TIB_ColumnBlob.LoadFromStream( const AStream: TStream );
var
tmpStream: TStream;
begin
tmpStream := Statement.CreateBlobStream( Self, bsmWrite );
try
tmpStream.CopyFrom( AStream, 0 );
finally
tmpStream.Free;
end;
end;

procedure TIB_ColumnBlob.SaveToStream( const AStream: TStream );
var
tmpStream: TStream;
begin
tmpStream := Statement.CreateBlobStream( Self, bsmRead );
try
AStream.CopyFrom( tmpStream, 0 );
finally
tmpStream.Free;
end;
end;
