Primitives have no names, but compound # objects have. # # Date Sun Jul 2 18:53:17 EST 1995 # Total 74 boxes # Time 256x256 darkstar, indicator bar # __________________________________________________________ #|sample 1 |sample 16 | adaptive | packing options |version| #|---------+----------+----------+------------------+-------| #|3" 25 sec|18" 45 sec| |grid (auto,2) | old | #| |18" 15 sec| |grid(3:4:1) size 3| 5.41 | #|1" 36 sec|16" 49 sec|16" 35 sec|grid(3:4:1) size 3| 5.42 | #+---------+----------+----------+------------------+-------+ # # ok ##################################################################
