libaec: libaec (Adaptive Entropy Coding library)
libaec:
libaec: Libaec provides fast lossless compression of 1 up to 32 bit wide
libaec: signed or unsigned integers (samples). The library achieves best
libaec: results for low entropy data as often encountered in space imaging
libaec: instrument data or numerical model output from weather or climate
libaec: simulations. While floating point representations are not directly
libaec: supported, they can also be efficiently coded by grouping exponents
libaec: and mantissa.

libaec: Libaec can replace SZIP.
