func NewReader

func NewReader(r io.Reader, mode, width int, inverse, align, LSBToMSB bool) io.ReadCloser

NewReader creates a new ReadCloser Reads from the returned io.ReadCloser read and decompress data from r. If r does not also implement io.ByteReader, the decompressor may read more data than necessary from r. It is the caller's responsibility to call Close on the ReadCloser when finished reading.
