 This archive contains 2 c2p converters written by Noe. Both
are very fast (actually I did not find any faster c2p for ppc).

Two functions are included:

VOID RGB15_TO_HAM6_NI(UWORD *RGB15, ULONG **Planes,ULONG Width, ULONG Height);
 Chunky buffer must be filled with 15bit rgb values (0rrrrrgggggbbbbb).
Conversion is done to first 4 planes plane 5 and 6 should be filled
with mask values:
   plane5 = 0x77777777
   plane7 = 0xeeeeeeee;
Remember that you need to open HAM6 screen (depth = 6), to use this c2p()

VOID C2P_NI(UBYTE *Chunky, ULONG **Planes,ULONG Width, ULONG Height);
Nothing fancy here. Simple (but fast) c2p routine. Converts 8 bit
chunky (paletized mode) to planar display.

Also look at HowToUse.c. There is an example (and a speed test) in C.

And if you can make this c2p routines faster - please contact us.

You can use this c2p routines for any purposes. But if you use it, 
please put my name in credit part.
