- Description
- -----------
-
- SHRI is an XPK packer sublibrary which implements a highly for
- compression rate optimized compressor, that uses offset/len encoding with
- adaptive arithmetic aftercoding for best compression results. Its
- compression rate is better than that of most other packers, e.g. lha,
- zoo or powerpacker.
-
- It supports 7 modes, which differ in the size of the dictionary:
-
- Modes Dictionarysize
- ------ --------------
- 0- 14 1k
- 15- 28 2k
- 29- 42 4k
- 43- 56 8k
- 57- 70 16k
- 71- 84 32k
- 85-100 64k
-
- A larger dictionarysize gives a higher compression rate but slows down the
- compression.
