Decompression algorithms
The decompression algorithms used in SCI are as follows:
SCI0 compression algorithms
method | algorithm |
0 | uncompressed |
1 | LZW |
2 | HUFFMAN |
SCI01 compression algorithms
method | algorithm |
0 | uncompressed |
1 | LZW |
2 | COMP3 |
3 | HUFFMAN |
SCI1.0 compression algorithms
method | algorithm |
0 | uncompressed |
1 | LZW |
2 | COMP3 |
3 | UNKNOWN-0 |
4 | UNKNOWN-1 |
As reported by Vladimir Gneushev, SCI32 uses STACpack (as described in RFC 1974) explicitly, determining whether there is a need for compression by comparing the size of the compressed data block with that of the uncompressed.
