DecodeOptions are the options used for the Decode process.
type DecodeOptions struct { Columns int Rows int K int EncodedByteAligned bool BlackIsOne bool EndOfBlock bool EndOfLine bool DamagedRowsBeforeError int }
Decoder is the implementation of the CCITTFax stream decoder.
type Decoder struct {
// contains filtered or unexported fields
}
func NewDecoder(data []byte, options DecodeOptions) (*Decoder, error)
NewDecoder creates a new CCITTFax stream decoder.
func (d *Decoder) Read(in []byte) (int, error)
Read decoded bytes from the input stream. Implements io.Reader interface.
Encoder implements a CCITT facsimile (fax) Group3 and Group4 encoding/decoding algorithms.
type Encoder struct { K int EndOfLine bool EncodedByteAlign bool Columns int Rows int EndOfBlock bool BlackIs1 bool DamagedRowsBeforeError int }
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.
