Filter API and constants.

h5py.h5z.filter_avail(INT filter_code) → BOOL

Determine if the given filter is available to the library. The filter code should be one of:

• FILTER_DEFLATE

• FILTER_SHUFFLE

• FILTER_FLETCHER32

• FILTER_SZIP

h5py.h5z.get_filter_info(INT filter_code) → INT filter_flags

Retrieve a bitfield with information about the given filter. The filter code should be one of:

• FILTER_DEFLATE

• FILTER_SHUFFLE

• FILTER_FLETCHER32

• FILTER_SZIP

Valid bitmasks for use with the returned bitfield are:

• FILTER_CONFIG_ENCODE_ENABLED

• FILTER_CONFIG_DECODE_ENABLED

h5py.h5z.unregister_filter(INT filter_code) → BOOL

Unregister a filter
