# Algorithm.lzbitmap

The LZBITMAP compression algorithm, which is designed to exploit the vector instruction set of current CPUs.

## Declaration

```swift
case lzbitmap
```

## Discussion

Discussion The LZBITMAP compression algorithm provides compression ratios as close as possible to COMPRESSION_ZLIB and COMPRESSION_LZFSE, with a lower compression cost. This compression algorithm is available only for the Compression buffer API functions, compression_encode_buffer(_:_:_:_:_:_:) and compression_decode_buffer(_:_:_:_:_:_:). COMPRESSION_LZBITMAP is available only on Apple devices.
