Libaec provides fast lossless compression of 1 up to 32 bit wide signed or
|
||
|
|
unsigned integers (samples). The library achieves best results for low entropy
|
||
|
|
data as often encountered in space imaging instrument data or numerical model
|
||
|
|
output from weather or climate simulations. While floating point representations
|
||
|
|
are not directly supported, they can also be efficiently coded by grouping
|
||
|
|
exponents and mantissa.
|
||
|
|
|
||
|
|
Libaec implements Golomb-Rice coding as defined in the Space Data System
|
||
|
|
Standard documents 121.0-B-2 and 120.0-G-2.
|
||
|
|
|
||
|
|
Libaec includes a free drop-in replacement for the SZIP library. Just replace
|
||
|
|
SZIP's shared library libsz.so* with libaec.so* and libsz.so* from libaec. Code
|
||
|
|
which is dynamically linked with SZIP such as HDF5 should continue to work with
|
||
|
|
libaec. No re-compilation required. HDF5 files which contain SZIP encoded data
|
||
|
|
can be decoded by HDF5 using libaec and vice versa.
