Gets or sets the filtering flags. This enumeration supports a bitwise combination of its member values. If a single filter is chosen, then that filter will be used for every row. If multiple filters are chosen, then a heuristic will be used to guess which filter will encode smallest, then apply that filter. This happens on a per row basis, different rows can use different filters. Using a single filter (or less filters) is typically faster. Trying all of the filters may help minimize the output file size. The default value is AllFilters.

Gets or sets the compression level in the range 0..9. The default value is 7.
