aec − compress or expand files
aec [−3] [−b BYTES] [−d] [−j SAMPLES] [−m] [−n BITS] [−N] [−p] [−r BLOCKS] [−s] [−t] infile outfile
Aec performs lossless compression and decompression with Golomb-Rice coding as defined in the Space Data System recommended standard 121.0-B-3.
|
−3 |
24 bit samples are stored in 3 bytes |
−b BYTES
internal buffer size in bytes
|
−d |
decompress infile; if option −d is not used then compress infile |
−j SAMPLES
block size in samples
|
−m |
samples are MSB first; default is LSB first |
−n BITS
bits per sample
|
−N |
disable pre/post processing |
|||
|
−p |
pad RSI to byte boundary |
−r BLOCKS
reference sample interval in blocks
|
−s |
samples are signed; default is unsigned |
|||
|
−t |
use restricted set of code options |
