pub fn forward_scaleoffset(
data: &[u8],
cd_values: &[u32],
) -> FormatResult<Vec<u8>>Expand description
Apply the HDF5 scale-offset filter (compress).
data is the raw element buffer in the dataset datatype’s byte order and
the result is the stored chunk: a 21-byte parameter header holding the
chosen minimum bit count and the chunk minimum, followed by the packed
values. Both the header and the compressed length mirror
H5Z__filter_scaleoffset’s forward branch, including its allocation of
one byte more than the packed bits need.
