Encoder implements a CCITT facsimile (fax) Group3 and Group4 encoding/decoding algorithms.

func (*Encoder) Decode

func (e *Encoder) Decode(encoded []byte) ([][]byte, error)

Decode performs decoding operation on the encoded image using the Group3 or Group4 CCITT facsimile (fax) algorithm.

func (*Encoder) Encode

func (e *Encoder) Encode(pixels [][]byte) []byte

Encode encodes the original image pixels. Note: `pixels` here are the pixels of the image where each byte value is 1 for white pixels and 0 for the black ones.
