Overview

Package rle2 implements a form of run-length encoding.

Index

• func Encode(syms symbols.ReducedSet, src []byte) []uint16
• type Frequencies
  • func GetFrequencies(syms symbols.ReducedSet, data []uint16) Frequencies

Functions

func Encode

func Encode(syms symbols.ReducedSet, src []byte) []uint16

Encode encodes src using the second run-length encoding form after the MTF transformation. The return type uses uint16 because it's possible to write values greater than 255 if the full byte range is used.

Types

type Frequencies

type Frequencies []int

Frequencies contains the number of times each symbol is used, the index being the symbol.

func GetFrequencies

func GetFrequencies(syms symbols.ReducedSet, data []uint16) Frequencies

GetFrequencies gets the frequencies for a slice of symbols
